I'm using it, mainly because it came free with my MacBook.
It does run under Rosetta, and I think this is most of the reasons why I don't like it, mainly because of the performance. I probably need more RAM (CompUSA is having a sale this week, so....). I have Quicken 2006, and I'm not buying any other until they come out with a Universal version. Rumor is for 2008, maybe you can hold off and see what comes out.
