I had the Note 4 as my daily driver for about 6 months and while I found the screen, battery and camera great. The lag was bad enough to jump to the G4(and this was after a reset). I do think the Note 4 has a better screen(brightness mostly) and better battery. With some tuning, the G4 battery is much better than what I was getting initially. I now can get 4 hours of SOT easily, as long as I am in a decent cell coverage area.
