You can throw my vote in for the OnePlus. I used to switch phones pretty regularly and since getting my OnePlus 2, the only phone I'd upgrade to would be the 3 or the new 3T. The one thing I absolutely loved was not having all of the bloat of the carrier apps on the phone when you get it. Totally stripped down and fully customizable.
