I have had both for over a year or so now.
In short, My partner knows nothing about gear, but when I switched the V67g for the B1 for a vox session,, his @ss could hear the difference and asked me why the vox sound that way.
I have yet to find a vocalist who sounds better on the B1 over the V67g back when I was really using them. But the B1 wins hands down on a guitar cab compared to a V67g for me. I get better results with the V67g on Acoustics though.
Both are good mics for the price. But since I got a V69, I havent really used either except for when we sometimes play around in the studio.
