30-06 vs 308 on large game
30-06 gets an extra 150-200fps with 180gr bullets which means an extra 50-75 yards effective range.
This means that ff 308 is a good 200-250 yards moose cartridge, then 30-06 is a good 250-325 yards moose cartridge.
270 Win vs 30-06 for the average hunter
This one is tricker but here are the facts: for a given sectionnal density 270 bullets are 20% lighter (270 130gr = 30-06 165gr and 270 150gr = 30-06 180gr).
This means that for a give sectionnal density bullet and kinetic energy level, you'll get a 20% reduction in recoil.
I think that 270 Win is better than 30-06 because even 30-06 150gr recoil level is too much for the average hunter (because of lack of training).
If you're a trained marksman, this reasonning does not apply and you might as well use a 300 Win Mag or a 338 Mag for large game!

Personally I think the .30/06 is a better choice if hunting heavier game but not by a lot. If a person won't make the effort to be able to handle the recoil of a .30/06 with 150 grain bullets in a standard weight rifle(very mild, indeed) then I think needlepoint may be a more appropriate pastime than hunting.
