what does a 6.5 creedmore do that a 6.5 x 55 doesn't?

[rpcw]

lol it's the same caliber as the 6.5x55 . The Creedmoor has firmly planted itself as one of the most popular cartridges on the market today. This won't change in the next ten years. Might as well jump on board and enjoy the benefits of this fine chambering

I am sure they are great but I went back and forth late last year between buying CM or X55 SE rather it seemed less versatile from a reloading perspective.

I just could not find any real benefit. I think I have owned 8 6.5x55 so I went for a T3x in that cal.

It is boring accurate. The CM would be as well....
