I've been in the same conundrum.
Initially, my thoughts were:
- Moto X would be the winner if it weren't for the battery
- Droid Turbo would be the winner if it weren't for capacitive buttons (some like them, I don't) and VZW bloat
- Nexus 6 would be the winner if it weren't for size
However, I went to the VZW store yesterday and got my hands on some of the larger phones (HTC One Max, Galaxy Note 3, iPhone 6 Plus). They actually didn't FEEL gigantic to me. In fact, I looked down at my Droid RAZR HD MAXX as I was walking out and was like "Wait, when did my phone get so small?"
I think I might be in the Nexus 6 camp when my upgrade comes next month.
Go to a store and try your hand (literally) at the larger phones. See if you feel the way I did (or not).
