Ask Dr. LJ - small business accounting for mac?

I have recently discovered that Quickbooks for mac has some serious flaws, and their tech support is not very, um, supportive. Is anyone using anything else on Mac for small business/personal accounting, and if so, what's your opinion?
Also - has anyone used GnuCash on any platform and have an opinion?

C'mon, I know you folks are an opinionated lot - let's hear it!
