I've only heard the earlier versions of both speakers, but I did have the chance to A-B those speakers pretty extensively and on more than one occassion. (I was considering a purchase a few years back, until I realized that a divorce costs even more than 101s.)
My take is that the 101 is a very different animal than it's its less insanely priced brethren. The football/pumpkin Mribib mentions made - to my ear - the 101s much more striking in the "omni-ness" of the presentation, as well as more impressively weighty and seamless in their presentation. OTOH, deep bass was always elevated on the 101s and less natural that the smaller guys. My net take: the 101 is a much more dramatic sounding speaker.
Some could argue that that is too much of a good thing. I happen to love the 101
