There are bugs in stock ROMs... When I had the stock firmware still on it (after rooting), vzw apps never worked, nor did wifi file streaming to ps3/tv. The latter worked for me when I flashed my first GB BaMF Rom and VZW apps works for me on CM7.
But as you know you can pick any rom you like and there are bugs NOT found in stock. I'm not saying stock is less buggy but vzw is responsible for those bugs. We have to depend on developers to fix bugs in their roms. These guys are super talented and generous but often move on to the next rom with the next version of sense before curing every bug in any existing rom. In fact between vzw network weirdness and buggy htc hardware it may be impossible to ever produce a bug free rom.
Every time I make up my mind to root and download a rom I read about some poor user who spends days looking for help (always available.but may take time to diagnose) just to get their phone functioning let alone bug free. If you need your phone 2 or 3 days of worry and lack of functionality is a big deal.
My only point is you can't complain about a camera bug (like burst causes fc) when someone is kind enough to share their hard work with you. The same bug would draw complaints from stock users (and should since we pay htc and vzw well to provide a quality, trouble free product.
