I love 7.0 so far. Loaded it up yesterday and everything just "works" better. Lag is gone, battery life is much improved, notifications work better, etc. My 5x was sitting as a backup phone since I hated the stutters I would get and lag opening apps. Battery life was also just OK even though it was new. It's like a totally different phone now and I plan on using it as my DD for a while to see how things go.
