Buggtussel Cingulates or B&W 805's or Proac?

I am looking for a pair of moinitor speakers. Can anyone tell me about Buggtussel Cingulates Specially. Or should I buy Cingulates or B&W 805's or Proac 1sc or Proac 2000 tablets? I might be asking a dumb question. But I don't know much about frequency or crossovers, etc..etc...

thanks
