In some what the same vein as the "30-06 is still a great cartridge" thread...
The .308 Win comes close, but the .30-06 can do everything the .308 Win can do, exceeds what the .308 can do when loaded to similar pressures and the .30-06 handles the heavies better. The .300WM also comes close but th e.30-06 has a much wider selection of factory ammo and with starting prices about 35% less than .300WM ammo.
Love my .22, .24, .25, .26, .28, other .30, .338, .375, .44 and .45 caliber rifles, but can't think of one cartridge that works better as an all-around option.
I think it depends on where you hang your hat. For most of North American, the '06 is plenty, Where big bitey-stompies are common, I'd like a 375.
