I've used both ics darkside and gb I went back to gb for better battery and stability. There are still bugs that need to be fixed in ics. If you need more customization and faster speeds you can go with the ever so popular juggernaut. Or you can mix juggernauts rom and save battery with the darkside kernal witch people seem to be doing the most.
