That's the same jump I made. Maxx to Turbo.
In my experiences, and none of ours are going to be exactly the same, I am mostly happy with everything about the Turbo. My two complaints are:
1) The camera. It is simply significanlty worse than the Maxx camera for unknown reasons. Taking pictures in similar conditions with either, the Maxx at its end took better pics, and that just shouldn't be. If you take mainly outdoor pics of stationary objects, the Turbo is superior, but things like our daughter's basketball games are far worse with the Turbo camera than with the Maxx. I am hopeful this is a software fix, though.
2) The battery. Yes, the battery. This one is a mild complaint, but the other one that registers in my use of the phone for the past 3 months. Again, I'm comparing to my use with Maxx and not to other brand phones, the marketing claims, etc. I just think my bettery should be a bit better than it's been under the circumstances. The comparison is reasonably controlled (same locations, same carrier, same apps, etc.). Again, this is something that with Lollipop's promised battery use may come off the list, and as I said it is compariosn to the Maxx, which blows away most other phones anyway. Mild complaint.
It's funny, when I go back and pick up the Maxx, it feels so good in hand. The Turbo is just big enough to be too big. I'm used to it, but the Maxx was definitely the sweet spot for me size-wise.
Anyway, enjoy your new toy! I'm sure you'll be happy with it overall.
