I think the choice of cartridge depends on what your intended use will be. I am a big fan of the 6.5x284 for deer/antelope hunting out west where my shots have been as far as 1000 yards. It carries 1000 ft/lbs of energy at this range. For my high volume target shooting, competition, and hunting in the east where shots are rarely over 500 yards, I like the 260. I just finished up loading up a bunch of 260 Rem loads for an egg shoot this coming weekend. I really like this round. It's very accurate, low recoil, long barrel life, and Lapua brass is readily available. My two primary shooters are a 6.5x284 Cooper, and a Savage LRP in 260 Rem. Good luck with your rifle, it's sounds nice!!
