My only thoughts are that it has been over hyped, and it doesn't quite live up to the hype.
I was a 6.5x47 Lapua before the Creedmoor came out. So I wasn't happy that Hornady came out with their own cartridge.
I have owned quite a few 6.5 Creedmoors since then I don't think there is anything magical about it. It is about as flat shooting as the 300 Winchester (not very flat) and nothing near what a 270, 6.5 PRC, 264 Win, 25-06 or anything else is.
Doesn't kick! So old men in their scooters like it.
Kind of like the 6.5 Swede it works, but isn't special.
Works very well for medium to small sized big game animals up to 400ish pounds within 400 yards. Gets less effective once you increase the size of the animal or the distance.
