As a hunting round it's adequate for everything but not really great at anything.
It's really splitting hairs to say any other cartridge is "superior" to the 308 Winchester. Yes, some may have slightly less recoil, and some may have one inch less drop at 300 yards, but for an all around hunting cartridge, you really can't beat the 308. I don't even own one, and never have. I have a 270 Win. and a couple of 30/06's, but I sure don't feel I'd be at a disadvantage with a 308 instead of what I currently have.
Better in what way? If one were to hunt to a max of 300 yards, realistically under 200 yards in the wet side, I don't think there is "better." There's different. There's bigger, faster, more recoil, more impressive on paper, but animals aren't impressed by paper stats. The bullet itself is far more important than the cartridge. Choose the right bullet for your hunting and fill your freezer.
Depends on your definition of "better," I guess. The headstamp on the cartridge is about the least important factor. More important is the actual quality of the rifle itself, the reliability of the scope, and as Taco280 said, the BULLET.
