B&W vs Martin Logan

I currently have Martin Logan Odessey/Theater/Aerius in my system with Krell amplification and processing. I'm considering a change. I've heard many good things about B&W. Could someone with experience with both tell me the pros and cons of each. If I go with the B&W it will be the nautilus 802's or the 800's for my main speakers, and 805's for the rear of our theater. My listening is about 60% theater and 40% 2 channel. Thanks for the advice.
