IMO - With any 243, 6.5, 7 mm, 30 caliber cartridge it becomes a question of how much powder do you want to burn and how much recoil do you want to endure. Choose any of them in a chambering you like with a recoil level that you can comfortably handle and go with it.
In my experience the less the recoil the better one can shoot.

This is exactly why I went to the 6.5 Creedmoor.
