Just a few thoughts having heard both speakers over the years:
1) The PMC is a very accurate and revealing speaker. I had a set of Celestions that were the same way and found that I couldn't stand them after a while. Most recording aren't that good and revealing speakes make them sound like crap. I found that I didn't like having 80% of my music collection rendered unusable.
2) B&W has a unique sonic signature. It is prevelant through their line. Either you like it or hate it.
Instead of looking at speakers based on their specs, why don't you figure out your price range and go look at some of the more popular designs. Vandersteen, Magnepan, Theil, Revel, Ariel, and many others make great speakers in the price range you are looking. All have their own unique attributes in the price range. Listen to them and you will probably find one that you love.
A final comment on accuracy vs. musicality. I think accuracy is far overplayed. No speaker is truly accurate and all have deficiencies. Rather than try to pick the one that is "most accurate", find one that has compromises that fit your listening needs best and buy that. In my case, I use Magnepans, they have many innacuracies, but I have not found any better compromise for my listening.
