I love the little 6.5 Creedmoor, once one realizes that the highest velocity is not needed for accurate long range shooting, then any of the 6.5s are equally capable. Now we will have Lapua brass along with Hornady, Norma/Nosler brass..
My 6.5 Creed, is holding 1moa or better out to 1000 yards with less than 10 mils of elevation, so I won't be needing the extra velocity I might realize out of the Lapua brass..
It all come down to appeal between the two with me, and I think the .260 is a ugly cartridge.
So that made my decision..
