I really like JJJ's line of thought that #50 was about completing the sixties, #100 was about opening the seventies, and #150 should be about the eighties. I'd love to see an eighties book like the Alpha Flight he suggests, or Wolverine or New Mutants.

Having said that, that's probably too progressive/unconservative for the Masterworks. So if I have to think seventies -- I'd have to agree that MTU isn't quality-wise the most exciting choice, although I can absolutely see its significance otherwise (and I do love the angle of starting a 150 issue run with MM #150). Qualitywise though I'd love to see Iron Fist Vol. 1.
