Plain old vanilla cm7. You can get it from get.cm. the latest nightly for our device is extremely stable. I personally prefer some of the ics roms that you can find around the dev section. Eagles blood, paranoid Android and hellfire sandwich are all ics roms that I have enjoyed using. Currently on Hellfire sandwich and am liking it however I will say I think eagles blood 4.0.4 aosp is the most stable of all the ics roms I have ran. Only thing that doesn't work that is relevant for me is the video mode for the camera and video playback is really crappy.
