Well, I myself am good regarding ROMs now.
Been using Validus ROM, Lollipop 5.1.1 based, for the last month, and I'm really happy with it.
Camera is not crashing anymore.
Phone not getting hot anymore.
Battery charging each 2 days, and even after 48hs I still have about 20% battery left.
Only issue so far is GPS - it's draining battery really fast (like, 4 hours straight with GPS and screen on drains battery almost completely). But I only use it this way in the car, so no big issue there - I just plug my car's USB cable into the phone and it's all good.
