I'm going to suggest that perhaps English may not be you native language?
If that's the case, perhaps introduce yourself as to where you come from and the kind of shooting you do and such.
That might help people offer advice that's easier to understand based on your local shooting type.
Those that have written about the 6.5 PRC, much like the .300 PRC all say that it is capable of excellent accuracy, however that is going to depend mostly on your rifle, barrel, bullet, load etc.
As for your point it's a matter of what you want to do when changing from .308
6.5 Creedmoor has less recoil and better aerodynamics than the average .308
The 6.5 PRC is a similar idea but designed to drive the same bullet faster, so you'll get more recoil, but have more energy and longer range.
The more recoil generally makes you have to work harder to keep your groups tight.
