I would disagree, the original question was will/how does the 6.5 Creedmoor outrun the 260 and 6.5X55. Answer to me it does not, outrun the 6.5X55. The 260 yes, due to the 260's magazine length. Then only beyond 120g bullets. I will admit I do not know the 6.5X47, but I do know the Swede. As to better, that is the question. What is "better", that is open to debate. Having a 6.5X55, and a Reloader I do not see anything better. Easier off the shelve perhaps.
My point is that if you cant get done with one you won't get it done with the others either.
