QuNect is definitely to be more fully featured because they appear to be creating a whole ODBC interface to the QuickBase API.
For me, I need a simple way to let SSIS query data out and pump data back in. I've not used QuNect, but if it's doing ODBC-compatible operations, it should be fine doing that and more. Honestly, the $2k they're charging is extremely reasonable.
That said - I can't (for funding reasons), spend $ on software, so I'm quickly writing a simple way to do some very simple interactions with QB. Nothing nearly as fancy or slick as QuNect, but it fits my basic needs and I'm happy to share it in case it might be useful to others.
