Just a couple of thoughts on this topic:

First, there's not enough difference between the 7-08 and 308 to build much of a hill of any kind, much less a hill to die on regarding which is better.

That said, it seems to me that the best way to judge a cartridge is in what it does best. I think the 7-08 bests the 308 in what both do best - sending mid-weight bullets where they're needed with maximum effect. In my admittedly limited experience and understanding, it seems the 7-08 shoots a bit flatter and with less recoil and more energy since the 7mm bullets make up some ground on the advantage the 308 has with a bit more juice.

If I want to send something heavier than 120-150 grains downrange with authority, I'm going 300WSM over the 308 or the 7-08.

In the sweet spot for the 7-08 and 308, I like the 7-08 a little better.

Man, I need to go shoot some hogs or something....grin.
