I might put a $20K Elam or maybe even a (gasp!) Stephen Paul -- moded Neumann somewheres up around the 8-10 range and what not as far as vocal mics go.
I'm assuming, though, that what you are refering to is in the same price range as the ksm.
And as far as that goes, yea, I'd rate it somewhere between 8-10, because it is one of the best in the $400-600 range.
But then so is the AT4047, 4050, BLUE Baby Bottle, and the Rode NTK. What you're talking about is a vocal mic, and vocal mics are very selective about what you point them at. The best vocal mic in that price range is whatever sounds best on that particular voice, given it's unique characteristics and nuances. Which could be any of the ones I just mentioned or something else entirely -- even something much cheaper.
A 10 on my voice might be a 2 on yours or a 6 on someone else's. A given mic might even sound like a 10 on my voice on one song, and a 4 on another song, depending on what range I'm singing in and what kind song it is. That's what makes choosing "the one" best vocal mic such an exercise in futility.
However, if you were to ask me, frankly, where I would rank the ksm32 on my scale of my personal favorites . . . or if you were to ask me what's the best all-around, all-purpose type condenser for instruments as well as some voices . . . I'd give it a 10. Nothing else touches it in that price range for drum overheads (including kick and floor tom), upright bass, guitar or bass cabs, brass instruments, you name it. It's just so good on so many different things. And it happens to be great on a lot of voices -- particularly female vocals, or wherever you need something very neutral (unflattering) and balls-on accurate.
