No doubt the S6 is an awesome knife, but I'm sure the SOD could do all the things you've listed and can chop better. It's only an inch longer overall and it's thinner, so as far as weight is concerned, I think they'll be roughly the same. But they will be completely different beasts, the SOD is the son of the dogfather, the chopping king in the yard, so balance will be higher. I can't wait for everyone to get it already so we can put it up to the test.
There is one area were the SOD will fall short compared to the S6. That is skinning, capping out game, on the hip whilst hiking miles in steep terrain. 1" is allot here.
I will also say, IMO I believe an all rounder starts at around 5" & ends at around 6.5", depending on the job intended, hand size & what floats your boat <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
