What phone to upgrade to from S3?

[duvallite]

Looking to replace my S3 with a new phone. I want something that is current and at least as good in ALL aspects, especially the camera and screen, for about a $450 budget. Any solid recommendations, especially from first hand experience?

The Oneplus 3t would seem to fit your budget... as long as you don't need a card slot... or a removable battery

I upgraded from my 3 year old and trusty S3 to the S5 last month. It's not the newest, but I wanted a removable battery and it does have Marshmallow (at least on Boost mobile.) I'm very happy so far. It has much better specs than the S3. It's faster, the screen is bigger with higher resolution, and the camera is better.
