In my opinion the 30-06 might be slightly more versatile. Don't under estimate the reach of the '06 either 165 grain bullet leaves the muzzle in the neighborhood of 2000 feet per sec. Don't forget GOOD CLEAR OPTICS , the gun can't shoot 300 yrds if you can't see out there.
Of course it would be ideal to shoot and see what you find comfortable. For a deer,antelope coyote ect rifle if your a smaller frame and not looking for the kick of the 06 maybe try the .270
