I've done both, and very slightly prefer buffalo. This isn't so much because of the animal but because of the country. As much as I love Alaska, it really isn't fundamentally different than much the rest of northern North America, especially many parts of Montana, where I live. Africa is very different in climate, plants and other animals than any part of North America, and the wildlife is vastly more abundant and diverse.
Funny, that was going to be my exact post (well, almost exactly).
The only African animal I truly desire to hunt is Buff. And I could spend my entire life satisfied never having hunted grizzly (or Buffalo for that matter)... but I'd prefer Buffalo.
