NEITHER is needed by anyone in the lower 48 states for anything..ALL that noise, expense of cases, extra powder, wear and tear in the barrel throat, RECOIL, RECOIL AND MORE RECOIL for a couple hundred feet per second..just no need.. the same bullet placed in the same spot by a .300 wm, wsm or saum will have the same results with far less of everything you mention above. FOR the average guy there's just no need, now if you into super long range killing from 750 up to where ever your equipment will take you, OK.. but for anything up to 750 there's just no need..a good ole 300 mkg out of my .338 wm will kill anything that either will hit beyond that will less of everything also..they are specialized and useful for sure BUT not for the average Joe hunter..
