As a non-American, early-adopter of the 6.5 Creedmoor, I simply cannot understand the anti-Creedmoor sentiment in the country that developed it!
This cartridge has been a leading factor in an era of unprecedented innovation and improvement in rifle cartridge ballistics - led by the USA. It's a fantastic entry-level cartridge for attracting new people into rifle shooting, and has proven that it can compete with some of the most successful medium calibres of all time (Winchester's triumvirate of .243, .308 Rem and .270), while offering match-level accuracy.
I cut my teeth hunting in the 1970s with my grandpa's open sight 6.5mm Mannlicher Schoenauer, but it was very slow & a nightmare to scope and I had to wait 30+ years to find a modern 6.5mm on true short action.
Since 2012 I've shot everything from Muntjac through Wild Boar, Mule Deer and Red Stags, up to Asiatic Elk with my 6.5 Creedmoor, and it's performed faultlessly. I no longer shoot 'at' animals, I place my shots on them.
I know 6.5mm used to be seen as a 'European' calibre, but surely Americans have got over that sort of prejudice! You guys invented one of the most successful new calibres in rifle history - why not celebrate it??
