I jumped on the 6.5 Creedmoor bandwagon last year. Bought a cheap Howa, loaded up some ammo, and shot some of the best groups I've ever fired. I also had a 7-08 and a 270, but I wanted to see what the 6.5 CM was about. No doubt it's here to stay, because it's a good accurate cartridge. But at the normal hunting ranges that 95% of us will shoot at game at, there will no difference between any of those 3, just as long as the shooter does their job correctly.
Still, I don't plan on getting rid of mine, and may even buy another one. It's too good to ignore. But, on the other hand, so are the 7-08 and the 270. Pick any one of those 3, and you can't go wrong.
Your post is way too logical. You are going to piss someone off... Just not sure who it will be though...
