I got real tired of 270win vs 30-06 when I was a kid and avoided them until now. I'm sick of the 6.5 hype, got tired of Jack O'Conner stories but it's not a dig on the cartridges. Past few years I finally acquired a 270win and 30-06 because they offered economy and availability in ammo and components compared to other things I've used. For me my main tools are all about logistics logistics logistics. For thelat reason it's 5.56, 270win, 308win, and 30-06 as primary firearm tools. Yes a 6.5 Creedmoor could fit in there but I just don't have a need for it
Unless you shoot at ranges much over 400 yards, the CM holds no real world advantage over your .270.
