I too have both. This is not what you're looking for, but the real answer is... you want both of them. They are different and quite complementary.
the 67 is, to my ear, a slightly darker or thicker mic. Great proximity effect, good for a "big" sound. Too muddy for some voices, however.
The B-1 is a jack of all trades. It's fairly neutral (for the price, of course!), moreso than the 67. In my room, it works better on a bigger, powerful voice because it doesn't accentuate the mids.
My 2 cents.
