As everyone else is saying, "better" is hard to say when you are comparing electrostatics with conventional speakers. I had some Quad ELSs for a while and absolutely loved them... please don't ask me if the M60s are better because it's a real apples-to-oranges comparison.
The 60s are more accurate, play louder, cover the full range better, handle dynamics better, all that "measurable" stuff... but the ELSs seem to give you decently good imaging without ANY sense of the sound coming from speakers at all.
I listened to Quads more than Maggies but the effect is similar... and in many ways the Magnepans (Magneplanars, whatever) are "even more different" because of their height.
EDIT -- I'm having doubts about one of the comments I made above... not actually sure if the Axioms handle "dynamics" better, come to think of it. You know that "microdynamics" thing that everyone babbles about ? I'm not sure what it is but I wouldn't be surprised if the Quads were better at it
