I just went through the same buying process. I'm installing two more pair of wall speakers tomorrow to dress out a Sonos network.

I listened to the MLCR's and the M6's from Sonance and both of the SpeakerCraft speakers. I went in biased towards the Modernos.

Both speakers had similar 92dB efficiency ratings and both were 8ohm, which is what I wanted. The Speakercraft had slightly better low end, the Modernos were a little brighter. If installing a subwoofer you can beef up the bass with that.

One advantage of the SpeakerCraft model was the adjustable tweeter. One room of mine has a tricky location and that seems like a selling point to me.

I did a fair amount of blind A/B and actually liked the SpeakerCraft better.
