I really enjoy both 6.5 Creedmoors I've owned. I've also owned a 260, and a 6.5x55. I've taken 31 deer with those 3 over the years. Honestly have not seen a hill of beans difference on game. Both Creedmoors have been more accurate with factory and handloads combined. When I owned the 260 factory ammo was scarce, and the accuracy of the 140 core lokts were dismal at best. The Swede was so so accuracy wise with factory loads. Handloads in the 3/4" range. Both Creedmoors routinely average in the 1/2" territory with factory loads, and sub 1/2" with handloads. The Swede is still my favorite due to its history. Just wish the one I had didn't have so much freebore. The 260 lost its case capacity by having to seat its bullets so deep to run through the magazine. I can easily hit the lands with my Creedmoors and still feed perfect through the factory mags, without spending more money on bottom metal to run aics mags,or wyatts mag box.
