Reply to Advice on upgrading canon rebel t5


I have been using Canon EOS rebel t5 for the last 6 years for fun, I decided to take my photography to the next level, I bought a canon lens 70-200 mm Ef 2.8 III, so what a good body canon camera that would be compatible with this lens? And also what the difference between mirrorless camera vs. DSL, which would have best auto focus and quick tracking any advice would be appreciated!
