Yep your right the bolt facing for those suggested are the same, as for what shoots better than the other we could spend all night going over the idiosyncrasies of each and achieve nothing.
I have spent allot of time this year going over the 3 cal's you speak of, quite a few hours of research opinions and wading though bullshit.
.260 and creedmoor are nearly the same but, now this is my opion based on research and a couple of test fires, creedmoor is better.
Creedmoor I believe, for the budget concerned, is cheaper to run than .260 hornady ammo off the shelf for creed is good stuff.
Now this is only my opionion and there are prob better educated ones out there, im willing to be schooled if you think im wrong
Here a link you may or may not have seen. 6.5mm Shootout: .260 Remington vs. 6.5x47 Lapua vs. 6.5 Creedmoor
