I currently have MIUI V4 flashed on my SGS2, it's really nice and looks very sleek, though still needs some work, it's not as smooth as the GB based MIUI was, some minor issues with the dialer, some freezes here and there, nothing too serious, though I wanted to try Cyanogenmod, and since I got a little experienced with the whole "Flashing a new rom" thing, I might give it a go.

Milestone (Droid), ICS support MIUI!
