Personally I think both are good rounds, and basically what one will do the other will do.
The 33's heavy is gonna be the 275 SAF and or 300 Woodleigh but I think the 275's it's best heavy. The 9.3's heavy is (I think) the 286 and I really don't think there's a hill of beans diff tween the two.
The 9.3's got a bit more weight but I feel that push comes to shove the 275/33 will give a bit more penetration.
Long ago I ran a 9.3x64 and liked it and think it's fairly close to the 375 H&H.
Lastly, I've used the 338/06 quite a bit and have only shot the 9.3x62 at the range so take that for what it's worth.
