Bose, the most recognizable name in sound...
would you purchase a bose system? Probably not and you shouldnt.
Dont base your decision on what seems to be better marketed or what you think should sound better because of the logo....
Klipsch does make some good stuff in my opinion, but only in the reference line...
I personally have not heard the EMP stuff but have read tons of great reviews and am familiar with some of the RBH products... and they seem a like a good speaker..
I wouldnt pay 250 for the quintets... I've stood up for Klipsch a lot on this forum, but NEVER for the quintets... not a good speaker really... as far as build/driver quality, frequency response, and lack of accuracy put it in the low-fi category as far as i'm concerned and much better can be had for the money...
