AB is good and was my ROM of choice, but it hasn't been worked on in forever. Some would say that's a good thing, but for not a flash-oholic like me. I'm using the latest
Gummy now. They are hinting at a new one fairly soon.
Nitro does good work. I used his ROM on the Fascinate. I've been tempted to use
his Charge one. I've never used
Danalo's stuff, but I hear good things.
They all have Gingerbread versions, but they are all based off a leak that isn't quite perfect, although perfectly usable and fast. YMMV
