6.8W xbolt sr looks pretty sweet to me. Some really good factory loads available for it and very accurate in my rifle. The christensen arms fft mesa looks pretty good too to run suopressor. Can get that one in 7 prc or 6.8W. I think both are good rounds and would work great. I personally prefer the 6.8W in a lighter gun as have had my fill of 180gr bullets at 2950-3000 fps in 30 cal magnums in light guns. In any case, The 7prc will not run the 6.8W out of town. There is plenty of market for both. The 270 and 7mm rem mag were both supremely popular for a long time after all.
