Personally, if avoid leasehold like the plague.
Generally speaking, I agree with you, but leasehold can be a bit like comparing apples with oranges.
Leasehold houses that formed part of an old estate/land interests
There are older buildings that are leasehold on 999 year leases, tend to be residual issue from old big estates, land interests. Ground rent tends to peppercorn or minimal amount. There can be quirky convenants about rights of access or what you can or can't do.
And one thing to look out for in older properties, say in a village or old parish, is ecclesiastical covenants, where there's a legal obligation to pay towards upkeep of the local church. Some people have bought a house and then found themselves landed with a bill for repairing or replacing the roof of a nearby church, although it's possible to buy indemnity policies against such eventualities.
Leasehold properties that are ex-council/social housing
This will tend to be flats/maisonettes, as houses are usually sold freehold - although a house might be leasehold if it's part of some communal heating system.
The pros are that the ground rents can be relatively cheap, eg my ex-council flat has a ground rent of £10 per year. And the service charges can be relatively cheap, eg service charge for my three bedroom second floor walk-up flat in central Manchester is just under £60 a month, which seems reasonable enough.
The cons are that every now and again you might be hit with a massive bill for 'major works' to replace windows and doors, or to replace a lift (I'd be wary about buying a leasehold flat in a building with lifts, as they're notoriously expensive to repair and replace, not to mention inconvenient if you live on the fifth or eleventh floor or whatever and the lifts keep breaking down).
Councils/housing associations are seemingly susceptible to contracting cowboy bodge builders to do works for them, which can be inefficient and expensive.
Another way in which they can be inefficient and incompetent is that when a leaseholder wants to do essential major works - decorating the block, replacing a roof, etc - basically anything that will cost each leaseholder more than £250, they are legally required to serve a Section 20 Notice and consult. It's 99.9 per cent of the time a 'con'sultation as they've already decided what they are going to do and which contractor they are going to use (even though they're supposed to get different quotes, this conflicts with their long-established practice of putting work out to tender and using the same contractors for all their building works).
Their incompetence can work in a leaseholder's favour, though, if/when they fail to serve that legal notice, because failure to serve the notice means that the bill for major works will be capped at the £250, so you won't have to pay more towards your eg £17,000 share of the costs for lift or roof replacement.
Many people who've bought under Right to Buy, or who've bought ex-council because it's relative cheap, have come unstuck by bills for major works and some have had to remortgage or even sell up due to being unable to afford a £15-30k whatever bill for their share of lift or roof replacement.
Leasehold property built by private developer
Leasehold houses are commonly known as 'fleecehold' because even though many property developers have offered purchasers the right to buy the freehold, even when someone buys the freehold they might find that there are still some covenants that aren't extinguished, like they still have to pay towards the upkeep of communal areas on a new build estate, like occasionally resurfacing a car park or maintaining playing area or gardening landscaped area, and people often complain that they're paying hundreds of pounds and not getting much in return.
But if you haven't bought the freehold, there will likely be lots of onerous charges associated with a new build (actually new, or recently new build in the last 2-3 decades), these will include above estate charges, but also lots of permission charges. Fancy painting your front door a different colour? If you're not precluded from doing so, they will probably charge you a permission fee for giving you permission to paint your own front door. Want to change your windows? Build an extension? Permission fees. Want to convert the integral garage into a bedroom or playroom or study? Permission fees. Want to knock your kitchen and dining room through and put in French windows opening onto your back garden? Permission fees. You won't be able to do anything to your own home unless you get their permission and pay for the privilege.
But worse of all is the issue of ground rent, which has been a cash cow for property developers. Many developers imposed ground rents that were due to be reviewed at regular intervals increase with the rate of inflation every five or 10 years or so, or some would double. £100 annual ground rent might not seem so bad, but if it's doubling, in 50 years, it's going to be £3,200 a year, an annual ground rent starting at £250 a year would turn into an annual bill of £8,000 due to doubling.
Lots of lenders consider doubling ground rent or even inflationary ones to make a property unmortgageable and you'd have difficulty selling to anyone who needs a mortgage.
And what's even worse is that a legal anomaly means that a ground rent of more than £250 outside London and more than £1,000 inside London means that it becomes an Assured Shorthold Tenancy. Do not touch with a bargepole. Now or if your increasing ground rent is going to put you in this territory any time soon.
Most people think of an Assured Shorthold Tenancy (AST) as a short-term let. It may come as a surprise, therefore, that long leases of say 125 years can also sometimes be ASTs. For a leaseholder, this won't always be good news.

The clue is in the word 'rent'.
But what this means in practice is that you will lose your home if you get into three months of arrears. Not might or could, but will.
If you get into more than three months of arrears with ground rent in (if your ground rent is in the >£250 outside London or >£1k inside London category), then a court
must grant possession to the freeholder. There is no discretion, no asking to pay of the arrears, nothing will make a difference because the law stipulates it. So you could lose your property. You might think you would be careful and not get into arrears, but 99 or 125 years is a very long time to trust that there won't be any bank-related IT glitches, that you won't change bank and forget to set up a new direct debit, or that you won't ever be skint/overdrawn and the payment won't bounce. And, again, if payments are missed, and you inadvertently get into three months arrears, it doesn't matter if you pay them off, the law says possession must be granted.
Some property developers are now addressing these concerns, and are now selling freeholds, or properties with more reasonable ground rent, but many developers have already sold on property portfolios to investors, some who increase charges further.
Service charges can also be expensive. As the residents in the building with the sky pool have found out, when they realised how much it was costing to heat their outdoor swimming pool.
The pool, suspended between two skyscrapers 35 metres above the ground, is heated with the £9,000 annual service charges residents pay.

If your apartment building has a swimming pool or fancy gym, secure parking, CCTV, concierge, etc, then you're going to pay through the nose for those, in service charges over and above monthly mortgage payments.
Cladding
And of course leaseholders in buildings affected by cladding scandal after Grenfell tragedy are facing ongoing uncertainty and potentially financially ruinous costs.
Conclusion
Some leasehold properties are much worse than others.
If you get an older property, with peppercorn ground rent and it doesn't have any weird or wonderful covenants like making you liable for the cost of replacing the nearby church roof, you're relatively okay.
If you buy an ex-council/social housing flat or maisonette in a walk-up building, it might not be too bad. NB a ground floor flat in a tower block also shares the cost of lift! But check when major works were last done and when they're next due.
New build 'fleecehold' is generally to be avoided, because of increasing ground rents and AST anomaly meaning risk of losing property (and capital invested) and also service charges for common estate areas and also expensive permission fees.
I'll come back to comment on shared ownership later, but I'm about to head out to work...
