There really is no "best" mike...
...but my own tastes gravitate towards "accurate" and "natural" sounding as being "best".
On that score, any of the Earthworks line seem to be well ahead of the field and under-appreciated. Everyone of their models is superior in accuracy to just about any other mike out there, and the models are just slightly different flavors of direction-pattern, sensitivity, noise, etc. Many of thekm sell for under $700. I would probably go for the SR77s, (hypercardioid) since I already have a matched pair of the omnis.
By the way, in spite of being ridiculed, the Carvin mikes are made by the same Chinese company and are identical innards to other mikes sold under more "famous" names. I suspect they actually sound pretty good, but i have not heard one.
Peace,
