I have a 6.8W and also a 270 wsm kimber montana with 1-8. I will probably do a 1-8 270 win someday but for initial builds preferred the slightly more case capacity of the wsm case in either persuasion. In the end I have gotten such great accuracy with browning and Win factory loads that I have not been compelled to load for the 6.8 yet, so though I reload for most, super accurate factory ammo is nice to me as I load for a lot of different rifles and rounds so can be a challenge to get to everything I want to with other activities. So I would personally go with the 6.8W. Much as you can do the same with existing rounds by doing non-saami things, Winchester has a nice out of box package to shoot high bc 277 bullets just like hornady did with 6.5 cm/prc.
