The two speakers have about the same "real" bass response -- and if you want to nitpick the M22 seems to have the tiniest bit deeper response if you look at the soundstage reviews. Having said that, the M3 has a slightly laid back midrange and a slight bass peak between 100 and 150 Hz and those two combine to give you the impression of fuller bass.

IMO it depends on the music you are listening to the most. If your preferences run to jazz, folk, small-ensemble classical and the like then M22s are probably the way to go -- extremely accurate and you'll probably never miss the deeper bass. If, on the other hand, you listen to a broader range of music you will probably find the M3s more all-round satisfying.

I would go with M3s myself, although my first purchase was M2s. With the M2s I decided I needed a sub, which then led me to the edge of the slippery slope of home theater. With M3s I would still be happily listening to my stereo system today and would probably have a lot more money.
