.308 is more readily available....do you reload? You need to consider all the factors, unless your really only care about ballistic superiority. The .308 takes the cake for me :D POWAH!

There isn't much that fits in the gap between the 6.8 and 308.

If you want to keep the same lower, try going to 7.62x39mm Russian.
