I think I will be satisfied, no matter which can I get.
Personally I think they are both very good. I don't think they should be compared to each other at all. They are basically apples and oranges. MS1's are open and leak, while RP21's are closed and isolate. MS1's are Grado's with the liquidy smooth mids and nice highs and great punch, while the RP21's has deep bass, less highs, and recessed mids. They are basically the perfect complement to each other (if you're under a budget.) I don't think one can say the one is better than the other, but only that they prefer one or the other. It's really all up to what you are looking for. Many of us have faulted where we recommend one over the other by saying one is "better," but remember it's all preferences.
Anyways...personally I think the MS1's are MUCH MUCH better
. I'm just joking around, but seriously, RP-21's just don't have that liquidy smooth mids I love, and the punchiness, and it may lack some deep bass, but everything else makes up for it. RP-21's to me have recessed mids, chalky treble, and clamp my head. Some could argue the pads on the MS1's may cause ear-ache, but you get used to it. Just my .02 cents.
Edit: And I just saw that you didn't like leakage. Too bad...you would have loved the MS-1's
