You know it just depends on whom you ask, right?
They could both sound great to you.
People who believe in speakers that measure well on Stereophile, Audioholics, Sound & Vision, Soundstage NRC, etc., usually don't prefer B&W or Klipsch (except the Klipsch THX Ultra certified speakers that have better FR measurements than any speakers ever measured on S&V).
People who don't care about speaker measurements or people who own B&W and Klipsch speakers will prefer these speakers.
Speakers that typically have better measurements include Revel, KEF, RBH, Salk, Philharmonic, Ascend, NHT, PSB.
I think B&W may have the best resale value, if that's important.
Klipsch (except for the THX certified speakers) may have an internet reputation of sounding "bright" because on the speaker FR measurements - they tend to have a "peak" around 10kHz region. But then again, this treble 10kHz peak is also seen in the expensive Paradigm Beryllium speakers and B&W Diamond speakers and the DefTech and GoldenEar speakers that others say don't sound "bright" at all. They may prefer this "lively" sound and consider the "flat FR" speakers as "clinical" or boring sounding.
