I have to vote for the .30-06 because of the two, it's the one I own and use. But I must admit that .308 cartridge looks nice!
When I hunted, I always used the '06--
--Now, I have three Weatherbys in '06, so, I can't really say I don't like the 308, I just don't own one--

I have a .30-06, but no .308 at the moment, so I would say .30-06.
However, and I think this is the most important thing about this issue: either one is an excellent round for hunting, or predator (the two-legged kind) control. When you've narrowed your choice to those to cartridges, you can't really make a wrong decision.
