Sound Quality: hard to say which one wins, but IMO the Momentums are very balanced and flat in comparison to the MDR-1Rs which are really mid-centric with a nice warm bass. So it depends on your tastes. I think I would personally prefer the MDR-1R sound over the Momentum for general listening, but the AKG K550 over both if I was looking for a neutral/flat sound.
Comfort: MDR-1R (over-ear) >>>>> Momentums (on-ear). the MDR-1R you can wear forever, but the Momentums get annoying after 2hrs-ish. however, if you are not wearing for extended periods of time the Momentums are comfy as well. Momentums are super light. It's really the on-ear-ness of the Momentums that bother me
Stylish: Depends on your taste, but the black/red MDR-1R are a lot cooler than the black/red Momentums IMO. If going silver/brown, maybe the Momentums are slightly better, but I don't really like silver/brown.
Build Quality: Momentums for sure. Momentums are lighter, real leather, stainless steel. MDR-1R is plastic, durable nice-feeling plastic, but still plastic.
Quality-Price: MDR-1R for sure. If you are super patient, you can find MDR-1R for <$200 which is a steal IMO. I think a MDR-1R under $250 is great deal. I wouldn't buy Momentum at $350. I know they use nicer materials, but the small earcup dimensions make the Momentum basically on-ear and I would definitely not pay more than $300 for on-ears.
Momentum's small earcup is a deal-breaker for me as I need to be able to listen comfortably continuously for long periods of time. MDR-1R is really extremely comfy. However, if that is not a concern for you or when you try the Momentums you can wear them for a long time without discomfort, then I think it would be a pretty even fight depending on your sound sig preferences.
