Here's my answer that sticks to the choices you gave in your post. I would highly recommend the 7mm-08 over the 30/30. In spite of it's history and the fact that it probably has taken as much, or more, game than any other caliber, the 30/30 just doesn't measure up to most "modern" cartridges. The 7mm-08 is MUCH flatter-shooting, exceedingly more accurate, has more power, with a much longer range capability, and is very reasonable on recoil. I don't own one, but my favorite rifle, that I have used for over 20 years, is a very close match - .280 Rem. It shoots the same .284 bullet at a slightly faster velocity than the '08, but not that much. With that bullet, I have killed cow and bull elk, antelope, and deer at ranges from 15 yards to about 400. I would not have been able to kill half those animals if I were shooting a 30/30. Get the 7mm-08.
