In my opinion the device specific roms are way better in terms of battery and performance. (I build AEX, POSP and Arrow). I recommend Arrow if you want something clean, AEX and POSP have more customization.
Only bugs you have to deal with are HWC disabled and signal indicator showing 0.
You could make a TWRP backup of your current PE setup. I removed all the sgsi's except for AOSP from my repo.
Thanks for the fast answer . I will install arrow because i want something fast and smooth. Besides HWC and Signal indicator, are there other bugs? (In PE i was facing a camera error 4 Times a Day so I had to restart my device often)
