I've just spotted this thread, surprised someone didn't tag me.
I wouldn't personally recommend Southwick, Shoreham is OK, but not a lot goes on there compared to Worthing.
Worthing has changed a lot in the 25+ years I've been here, it's certainly no longer 'God's waiting room', it's recently featured in various national magazines and newspapers as being a hot spot to move too. As people say, London is moving down to Brighton, Brighton is moving to Worthing. To show how it's changed, Labour took control of the borough council a couple of years ago, for the first time ever, coming from having no councilors on it about 5-6 years ago.
The trains are good to Brighton, it's a fairly small borough, but we have a total of five train stations, times vary as to which station you use, but it's about 30 minutes to Brighton, and then fairly fast onto Gatwick. The 700 Coastliner bus service runs every 15 minutes Mon-Fri daytimes & 20 minutes on Sun, journey travel time around 50 minutes, the N700 night bus runs Fri & Sat, with the last bus leaving Brighton at around 3.30 am Sat/Sun mornings. Probably about half those times to get to Shoreham.
There's plenty of good pubs & restaurants, independent cafes and shops, art galleries/artist studios, a growing live music scene, and a few clubs, a museum, two cinemas and two theatres, long & pleasant prom, you can walk or cycle on the coastal path to Brighton and certainly as far as Littlehampton in the other direction, and there's a lot of events put on, especially during the summer months, with many being free. Good hospital and schools too. BTW, the dive club's boat is actually moored in Littlehampton, about 15 minutes by train/20 minutes by car. Plus we're right on the edge of the South Downs National Park, in fact the very north of the borough is in it! It's one of the sunniest places in the UK, hence being known as 'Sunny Worthing'.
The
Time for Worthing website is a fairly good resource to get an idea about the place, and the
Worthing Sailing Club may be of interest. These are just some of the recent reviews in the national press -

The major drawback is the anti-social psychotic airborne scumbags, AKA seagulls, but you'll get those bastards anywhere on the coast.
