As stated above, the only real difference is ammo price/availability. Both cartridges are fairly equal in terms of performance, and should do just fine for anything you hunt on the dark continent. My father has a .416 Rigby ( sold his 458 to buy it) and shooting it is tolerable, off hand. Shooting it off a bench is about the worst torture I have experienced, you really need to be able to roll with the recoil with that cartridge. Factory ammo does pretty well, but you can really crank things up with handloads. Having put many rounds thru both his .416 Rigby and .458 Win, I think for my big bore, I will stick with the good old .375 H&H. (Although thoughts of a .404 Jeffrey cross my mind a bit, just for something different) The .375 has very tolerable recoil, cheaper to shoot, you don't have to pack around a 12 lb rifle, and it still gets the job done fine, just ask Finn Aagard, John Hunter, Peter Capstick, etc.
