Choose anything based on stock & you're good to go. I know it is hard to find good roms when you're a newbie but please try to experiment & read some reviews about the rom before posting threads like this. You are experienced with galaxy y & you must already be knowing that such threads aren't encouraged here.
Anyways, take care from now on. To start with, try our myth roms, spacecaker's sgs2/sgs3,stocklite v8, galaxy ace unlimited, touchwiz ux by nathan, etc.
