M22 vs M3 (another thread!)

A subwoofer isn't an issue at all, I have an old Yamaha dual 8" subwoofer and a SVS PB12-NSD sub, I'll probably end up using the SVS :p. But what I care about is which set of speakers have more of a roaring midrange for the electric guitar and overbearing male vocals.

For the time being this will be used near field with a 6-wpc tube amp. In the not too distant future (fall of this year) the speakers will be paired with a 38-wpc tube amp not too much further than near field (eg ~6' away or so).

This setup will be used almost exclusively for 2-channel music. I would order the M22's and be done with it, but I don't know why I have the feeling that the M3's would be the better choice.
