I have had both. Rum is about 75 fps faster in the weight bullets I care about. I have no favorite between the two. I reamed the 300 wby up to a 416 Rigby with no case taper and a pushed forward 40 degree shoulder. For all practical purposes, its a 30-378 Wby now. My favorite .30 Cal is the Win. Mag.
Between the two cartridges you asked about, to me, it would all boil down to whether you like a 700 or a Mark V better.
I have two Mark V .300 Wby rifles that have never been shot. I bought them for their actions. $435 at Walmart several years ago. (long story but I bought 8 of them)
