Definately the 375 H&H. Unfortunately I've never seen a bear while hunting for one. They always seemed to pop up during the most inconvenient time, but honestly that 375 is the very least I'd use and they're not bad to shoot either.
A friend of mine many years ago went bear hunting in the Adirondacks and his friend shot a bear 3 times with a .338 mag and it grunted after each shot while walking towards a stream. My friend finished it off with a .44 mag blowing it's jaw apart. I'm sure it wasn't pretty and I'm glad I wasn't there to see it.
