I started with the M22s and later upgraded to the M60s (just because I wanted tower speakers). I thought both speakers sounded great. In fact, I'm still using the M22s as surrounds for multi-channel music.
If you do not plan on upgrading your sub, you may want to consider the M60s. They do a really good job...even without a sub. If an upgraded sub is in your future, the M22 may be the best bet for you. However, if you plan to buy stands for the M22s, the price difference between the two isn't as significant.
