I have a Droid Turbo II that is a warranty replacement for the original Turbo I picked up last fall. I liked the Turbo but it took a crap a few weeks ago while charging and burned up the charging port and cord.
I like the Turbo II as well, but yes it is slightly on the large side, which is fine by me as I have large hands. Like most new phones it is pretty stable, its camera is probably still not quite up to the Samsung standard though. My GF's Samsung takes better pics. Other than that I think they are pretty similar in durability. I wear mine on a hip holster instead of the backpocket chick move.
Personally, I hate small phones. Not because I have trouble using them, it's because everyone I talk to that has one finds a way to cover the microphone when they speak and it sounds like they are under water.
