Their fantasy football platform, at least, is the best of the ones I've tried. Lots of obvious product placements and ads, but good UI and UX, well-gamified weekly/seasonal trophies, and interesting statistical stuff I haven't seen anywhere else.
I agree, it also does a lot of little things right that other platforms mess up. For example, it's the only platform that doesn't penalize a team's defense for scores that occur when they're not on the field (e.g. an interception returned for a touchdown). It is, unfortunately though, an unholy browser memory hog as well.
