Having owned and shot many of the mentioned "rounds" and loving every one of them, I have simplified my life to owning and shooting 1 rifle and round. I have a Browning A bolt SS Stalker in 375 H&H. In NA I like the 250gr or 270gr softpoint. I had it Magna ported and can say that the recoiled has been tamed to the level of a 30-06. Only negitive is the 26' barrel, but I have gotten use to it.
I think that whatever flavor you prefer, the one thing that all of us agree on is that you must be able to handle it and shoot accurately under all conditions!
