Wildlife Lens for R6Mii

[Ovacheerdad]

Looking at picking up a lens to shoot birds and other wildlife with. I know some of these lens’s pair better with crop bodies like the R7, but my current body is an R6Mii.  I would prefer the Sigma’s over Tamron because the zoom ring rotation. Do all Tamron’s turn opposite of Canon and Sigma? I know this is quite a list but as I read through posts and articles, I take notes as to what people are using and these seem to pop up a lot of the time. If you had to pick the best one out of these as far as reach and sharp images which, would it be? Or I’m open to other suggestions as well.

Own the Canon RF 200-800mm F6.3-9 IS USM with the R6Mark II.  Great value IMO.  No regrets.  Took it as my only lens to the Everglades and Key Biscayne last fall and had a blast.  Any shortcomings are my own, not the lens.
