The 7D2 is an excellent camera and I would have no issue using it only. However as I have said before I feel the 5D4 edges it out in IQ. Fine details, cleaner files (although you can work with that on the 7D2) and better for crops. I have all AF points available at F8. The 7D2 better AF point coverage in the viewfinder due to sensor size which I prefer. The 5D4 could use a few more FPS. That would have made it an almost perfect camera. As for AF speed and tracking for BIF I'm still on the fence. Every situation is different so I can't really say for sure. I rarely come home empty handed with either body.
I think when we see a crop sensor and its ability compared to the latest 5D series and it being a draw (even if the image q goes to the FF by a bit), I think the 7DII is a performing bargain. After how long the 7DII has been out? I'm happy...
