First of all, I'll be quick to say that any way of sorting out the best owners in this game should exclude me. I just mess around and learn what I can and occasionally sniff my way to a good roster. But focusing on the active guys with the most titles (or highest percentage of titles per teams entered, with a minimum number of teams) would be more meaningful, since some of the guys in the top 25 haven't run very many teams and stick to open leagues where the competition is less fierce.
On a pragmatic note, we'll just be lucky if this thing fills.
And having said all that, by all means call out the top 25. It'd be interesting to see what happens.
