Bought the 3T with the intention of selling my 6S, but I can't let go. Love the form factor of the 6S; macOS integration, camera, FaceTime, iMessage, security, not as many pop-ups. But now I remember why I loved Android; customisation, openness, keyboard. And in regards to the 3T specifically; the large HD AMOLED screen, the gestures, OIS, front facing camera, split screen, Google integration - was Gmail and Google Music when on my iPhone as well. Kinda torn right now. Might build a spreadsheet. Maybe I could rock the two of them... actually, those who do that, do you have two separate SIM's or do you keep alternating between the two devices?
