Reynolds you are correct, the real world application and performance between the two are trifling. I am however a nerd, and love to analyze the minute details between cartridges.
Creedmoor Max Loads:
From Nosler's new reloading manual:

A practical difference between the 260 Rem and the 264 Win Mag, in a 10 MPH full value wind, you will have about 4" less wind at 600 yards (4.5MOA/28.5" @ 2700 FPS vs 3.8MOA/24.2" @ 3000FPS) The Creedmoor would be a little worse, but not much.
140 grain Accubond loaded to max with 44 grains of Hunter is 2730 fps
From Hornady's 8th Edition:
With 140 grain A-Max or SST loaded to a max with 41.7 grains Norma URP, 43.2 grains of Winchestor 760, 42 grains of RL-17, or 42.6 grains of Hybrid 100V you achieve 2725+ fps.
