.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 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.
