Not a lot. Case capacity and length are for practical purposes the same. No belt on the WSM, plus only Remington makes 6.5 Rem. brass and it's a seasonal run. Remington, Winchester, Norma, Federal, and Nosler carry 270 WSM brass. Some would say that having to neck down 270 WSM brass is a disadvantage but it's no big deal, I run new brass into the die to straighten the necks anyway.

As far as barrel life I don't know but it is directly correlated to the volume of powder and pressure. On my 270 wsm I load it like it is a 270 AI and suspect I will get at least 2,000 rounds. That's way more than a 6.5 x 284 but most are loaded really hot by the 1000 yd bench crowd.

Loads in the 63-65,000 psi range will generate more heat and wear and it increase with each step down in bore diameter.
