64gb white AT&T. So far it's been great, battery seems to be a bit worse than my previous 4S, maybe I'm just using it more. Came from a 4S, a 4, a 3GS, a 3G, and and OG 4gb, tried a few other phones over the years, a gs3, a lumia 900, HTC Titan, HTC inspire, Dell Streak, bold 9000.... Always come back to the iPhone though, the apple ecosystem is great, kids have iPod touches, have 2 apple tv's, every movie we buy for the past few years is on iTunes as its so easy to load them on their touches for car rides, or put them on the Apple TV at home, there's always been a few hiccups here and there, but overall apple offers the easiest to use ecosystem out of them all.
Sorry for the long post, but I just love typing on my iPhone 5!
