I don't like talking specific mics - as one of the above have noted already, they are creative tools. Every guitar or voice will sound particular different and every mic, or better suited for a mic that you'd never think would be amazing. A lot of Condenser mics can be used to replicate a ribbon mic's pick up pattern. And most are rather in-expensive.
Grabbing a mic, for a home studio or home applications should be inexpensive, and might as well grab up a few. I have a AKG 200 Perception, Behinger B2 Pro, and have worked with Audio Technica 4040, SHURE SM58's and Rhode NT1 and NT2. All very amazing mics. B2 Pro and NT2 have figure 8 pick up capabilities.
All comes down to mixing people...
It's always and for ever will always be about the mixing.
I have used shitty ass Sony Omnidirectional mics ($50) and made amazing sounding vocal tracks.
ITS ABOUT THE MIXING DAMNIT!
