Sounds reasonable to me. That's why I didn't badmouth the Gen 4. I thought it was the G17 that was experiencing problems and I think I read that Glock was in the process of rectifying the problems with a lighter recoil spring. Nothing that would scare me away from one, for sure. It sounds like the G22 was good to go out of the box.
I'd say my first consideration would be the feel, because I think it's important for a gun to feel good in your hands. Apparently, the adjustable backstrap cures the clunky feel of a Glock for folks with smaller hands. Fortunately, I never had a problem with that.
After that, I suppose the only other obstacle would be the difference in price. I see 3rd Gen G22s going for $400-450 all the time. That might make a thrifty person like myself opt for the savings over paying around $550 for a 4th Gen.
As far as accessories go, I wouldn't worry too much about that. Glock has always been pretty good at keeping things compatible and there are way too many older Glocks out there for them to leave us behind now. I'm not aware of any add ons that are exclusive to 4th Gens. If I had to venture an educated guess, I suspect the 4th Gens are like all the other Glocks in that about 95% of the parts are interchangable with any other Glock of the same deminsions.
Don't over think the situation, though. Research is good, but over thinking can drive you nuts and usually always causes me to second guess myself. Keep things simple and enjoy your new Glock. You won't regret buying one. I know I never have.
