The declining number of specialists who can whip an MFI system into shape vs. the tens of thousands who can "tune" CIS is an argument in favor of the latter. MFI has 14 adjustment points, and once they are all set, you go back through all 14 again, and maybe again, still. CIS has one hex head mixture screw.
That being said, I doubt most of us are drawn to early 911s for the convenience or economy. Given the choice between two roughly comparable 73 Ts - one MIF and one CIS, I would choose on the basis of other merits than the injection system.
