In my opinion, i would choose the 270 shooting a 130 grain Nosler all day over the 7mm. The 270 - often called "the poor man's magnum" or the thinking man's gun" is very close to 7mm stats. I had two different 7 mags and really could not see a significant performance factor over the 270 + the benefits of the 270 - ammo available everywhere, less expensive to shoot - and while recoil doesn't bother me it certainly is less and you can shoot the darn thing all day.
If I were going Mag I would go 300 win mag. Just got a new Tikka Lite in 300 wm and I can not believe out of the box how good of a shooter it is. I have no second thoughts about getting rid of the Weatherby + I am really not fond of the short mag theory....
