If you want to go back to Touchwiz, you will first need to flash philz kernel & recovery (unfortunately I can't post the link on this app but its easy to find here), then reboot recovery and flash your TW ROM. As for my personal opinion, definitely AryaMod, it is both feature packed _and_ quick, with the advantage of a buttery smooth launcher.
