The usual plastic poppers on duvets are shit, tbh. I replaced all the crap poppers with decent metal snaps and bought a tool for the purpose. I have such a thing called a gingersnapper - around 40 years old and was used (as a home sewist) when those shirts with pearlised poppers became popular and babygros became a thing, but I can't find the right studs for it so I mostly just use a Prym press-stud fastener.
I don't like buttons, vecro, or flaps - all have their drawbacks. Zips are effective, but hard to find a zipped duvet cover. If you are going to have poppers, I definitely think they need to be sturdier than the plastic ones...which invariably fail to properly connect.
