I'm going to jump in here with my limited knowledge of 6.5mm's. I choose the Creedmoor, and not sorry I did. I've been a handloader over 60 years and have never found a cartridge that was easier to load for than the 6.5 Creedmoor. In my opinion it is by far the easiest cartridge I have ever loaded for accuracy. The rifle is an off the shelf short action Rem 700, that can be found in any gun shop in the country, nothing custom. It will consistently produce 3/8" five shot groups at 100 yards off the bench. Love my Creedmoor!
