What is your tastes? What kind of music do you listen to mostly? Do you listen loud? Are you going to sit in the nearfield or farfield? How big is the room? Each of those speakers were designed to work in a specific way. For instance the two Wilson speakers you mentioned are redically different designs of Dave Wilson's. The B&W and Revel speakers are wide dispersion designs that will sound just okay if placed close to side walls. If you're room is normal I can't see you going wrong with any, but your speacial circumstances would dictated the decision. Me personally, I'd go with either the B&W's, or the Revels as they both have very good power responce's. However, if you listen at lower volumes the Revel's will sound fuller.
Have Fun,
