I'd take the old '06 hands down. More commercially loaded ammo than any other caliber. Handloaders dream. More bullet selection than Carter has liver pills. 50 bucks and a competent gunsmith, the '06 can become the Ackley Improved. Turning the ol '06 into a .300 H&H., yet you can still fire standard 30-06 ammo!! I have a custom rfle in 30-06 Ackley improved, would not trade it for my wife......well something like that. Even Col. Craig Boddington (Guns & Ammo Writer) states this as his one gun favorite. Besides, I have always preferred the sectional density of the .30 over the .284 bullet. Lots of room for argument here. What do you other guys think?
