Looking to upgrade from my Moto G3 to something much nicer

Hello,

I'm looking to upgrade my phone after a couple years living on the cheap. My Moto G3 has taken me about as far as it can go unfortunately. Here's what I'm looking for:

1. Great camera (I'm consistently envious of my iPhone friends' cameras)
2. Solid battery life (I charge most nights but it'd be nice to end the day at 50% with medium use)
3. I do prefer stock Android, but I'm not completely against something else.
4. Something that will likely get the next version of Android.
5. Not Samsung. I just don't like their look and feel. Nothing against people that do.
6. Oh and T-Mobile Band 12 support is a MUST!

Price can be on the low or high end, just so long as it gets what I want.

I'm sorta looking at the Pixel as of now. The unfortunate part of that being that a new one is only a few months away and the current one is still full priced so I'm not sold on it... yet.

Any help is appreciated!
