I used B3s exclusively for a couple of years, when I didn't have the money for Sankens or DPAs, and I think that the B3 gives some of the most honest reproduction out there. They are more difficult to hide, and I had to have the connectors re-terminated more often than I would have liked (but thanks to Mark at Location Sound Corp. for his expertise or I would have been sunk!). The difficulties, though, never outweighed the quality. In my opinion, the B3 (standard sensitivity, Flat Response Cap), was far better for narrative dialog than several other mikes that I've tried in it's price range (TRAM TR-50/Sonotrim STR, PSC Millimic, Sony ECM-44B). And the B3 is very versatile, I've even used B3s for instrument miking with relative success.
