I would rank the MBI made MCC at the bottom as it has been reported by a moderator that MBI's media code does not confirm to the standard of the rest of the MCC and, as such, they do not burn well at all. I have burned the Prodisc MCC 004 and they are not as good as the CMC, but they are cerainly a very good burn.

And yes, the PAPA serial are CMC.
