Ballistically the 30-06 has a tad more pep but all in all, I for one, don't think there is that enough difference to get too excited over. If I am not mistaken, both use the same bullets so the only difference is case size and amount of powder used. The 308 seems to have more of a following in the target shooting world due to short length cartridges being slightly more accurate while the venerable 30-06 is the numero uno cartridge for big game with the 308 also having a very strong presence.
You can go to almost any of the cartridge manufacturers websites and look over the differences in ballisticsto see if if would make a difference for you for target shooting. For deer hunting, it is a tossup provided you use properly constructed bullets and proper marksmanship. If possible, try both cartridges in a friend(s) rifle and see which you prefer. A nice thing about both cartridges is that nearly all actions are chambered for both giving you a very good selection to choose from. I seriously doubt that you can go wrong with either cartridge for what you described.
Or you can do what I would do, I already have a 30-06 and am looking for any plausible excuse to get a 308.
Good luck and safe shooting.
