Yahoo has an easier to use interface, better drafts, and better stats when you use stat tracker. It also does have a league message board, league rankings, and league points, which are like power rankings. I don\'t know what you mean by weekly team comparisons, but you can see the matchups on yahoo. Yahoo is the easiest system to run effectively. And all the real time stats and such are available, on stat tracker, which is a great system, for only like $8 a year (which is well worth it, especially if, like me, you\'re in 4 yahoo leagues).
