This is all extremely subjective. But for leading, I'd be interested if you gave 10 crappy noobs with one leader, and 10 crappy noobs with another, and did a 1v1, who would win? Not that I'm not biased, but CommissarJDF always had pretty bad skill-wise overall groups, yet he could win mid-leagues and even beat some tier1 regs once in awhile in a non-league 1v1.
