While Urchin may give richer results (because it can access more data), GA allows for advanced segmentation, benchmark analysis, and event tracking.

This is speculation, but depending on the configurations it's also possible that Urchin is more aggressively dropping hits from spiders, at the same time that more spiders are becoming JS-aware and thus increasing GA numbers (unrealistically). 

There are a lot of other possibilities, but that's one thing I'd been pondering recently based on some similar observations.
