While I liked the couple of 7mm08's I've had I never totally fell in love with them. In fact my last 7mm08 I had rebuilt into a fully custom made rifle chambered in 6.5 Creedmoor. No regrets the Creedmoor is an absolute pleasure to shoot. Very accurate, low recoil, and kills stuff dead. As I get older I appreciate less recoil more and more. Out of all the calibers you listed that you own the only two I haven't owned are the 6.5 Weatherby and the 270WSM. Not that I wouldn't have wanted to own either, but by the time they came out I was over my magnum rifle phase and I don't see me ever going back to it.
