My biggest issue with Urchin is that it seems to track things very differently than Google Analytics. The counts are significantly higher, and I'm not sure that it's properly filtering out the things I want filtered. Maybe that's my personal issue, but Google Analytics has a lot more support for troubleshooting, and finding answers.
I also think the interface is significantly more difficult to use in Urchin.
