I like Leupold myself - have one on every rifle I own now. For big game hunting with a 30-06 I think a good all round scope choice would be the Vari-X III, 1-1/2 - 5x, or a
Vari-X II, 2-7x. Don't get hung up on more magnification. Unless you plan to use your
'06 for varmints also, these provide all the magnification you'll need for deer, and larger
game.
