which camera to buy?

I'm a beginner and confused what camera to get whats your suggestion over nikon d7200,canon EOS 80D and sony A6000?


I'm partial to Canon, but that's just what I use and have lenses for. I'm able to use the lenses my dad had for 40 years on my contemporary DSLR, it's awesome. I've tried the Sonys and they are pretty intuitive, but they go through batteries FAST.
