It's by far the most used, well known, durable, sturdy, good sounding live mic around. There's not a single tech who doesn't know how it reacts and sounds. There's not a single stage anywhere in the world with a bunch of them ready to be used. Or abused, it never fails.
But, even if it's the standard that everybody use as a term of comparison, it may not be the best for YOUR voice.
I don't love it with mine for example. There's a thing on mid frequencies that doesn't marry that good with my voice. I prefer other similar priced mics, sometimes I prefer singing with a 57.
So it may not be the best for you, but you must start from here, it's the number 1 of any mic arsenal, along with its cousin SM57.
