i personally didnt like it much either, i have used NeatRom, omega and WanamLite(installed it not really used it much). Like neatrom the best. It would be a good option for you to flash siyah kernel and keep the stock 4.1.2 on the 1st rom and try installing roms on the 2nd so u can try it and see without loosing all the data.
CWM won't backup your efs folder, but an app like kTool -
- its a good middle ground between sammy and aosp imo
