hey doc,
The behr.(at least the one I tried) is a very bright mic, it sounds good on, hmmm, a nylon string acoustic, or something that needs to a bit of accent on the high end. Not bad for overhead in some cases. I didn't care for it on vocals. Needed too much EQ to keep it in check, Comes in a nice box for the money, with a shockmount, and who knows, maybe you find a use for it.
The SB is thicker sounding, I didn’t use one myself, but one of my associates let me hear a track he did with it, It’s better suited for vocals in my opinion.
All and all they are both good deals, for vocals I’d rech for the SP
