Well, my last ROM was stock 4.0.4 supercharged, 3G speed-touch-video-overall speed tweaks, and it was a good one (normal stock battery drain).
Now I'm using CM9, the speed and smoothness is impressive, there's absolutely NO lag. But, battery drain is absurdly excessive. So, it's perfect if you like to charge your phone every 2 hours.
Now, I'm gonna try JJ ROM with Arc Knight kernel. Let's see if it have a good (general) response as CM9 and normal battery drain like stock.
