I was in that same boat. I recently switched from SS 5.3 to Project Elite v4.2. Wiped everything. I flashed and didnt restore any old apps besides the one on my account. Battery life is extremely good. Recently loaded the v6 supercharger script and its pretty responsive. When it asks you for choice 1-16 choose 3 and then reboot. Themes are pretty easy to apply and I havent had issues w/ anything (camera, market, LED, etc). Idk check it out if your searching, worked for me.
