This is a confusing question. What does the 10X have to do with how a MC compares to an US?
In any case, I can tell you that the MC and SL-20X are very similar, with the MC having adjustable focus, more artifacts, better throw at tightest focus, and HA coating, and the 20X having less throw but more light (with 35X LA installed) and a fixed focus. The US will undoubtably have more throw than the 20X, but other than that I don't know and can't say.
The 10X, however, will blow the MC or US or 20X away. No contest. The MC probably throws farther, but who cares? The 10X puts out such a "wall of light" and the MC casts a pencil thin, laser-like beam (at tightest focus), that I'll take the 10X over the MC any day.
