Time To Upgrade.... What do you recommend????

Hey Guys whats up. time to upgrade my phone. What do you recommend One should get?

I am stuck with ATT for now guys as I am the Card Holder, and my family is all under my name.

I was looking at the Note 5, But after Reading you will not be able to Root the phone. And I am one who likes to use Custom Roms, build roms, and so forth.
