you have your stuff on X360, the XB1 is your natural choice, you character(s) carry over, I have both and play on both but I'm giving up on the XB1 version, exclusives are my reason as well as I have a dedicated group to play with, not so on the Xb1, I land up being a 4th or 7th stringer, and 3-4 sets of bounties gets old fast! If you get a PS4 your starting all over, PS+ is required.
