Fingerstyle? Andy Mckee.

And yes Acinod, that kid is amazing haha. In a lot of his earlier videos he looks depressed, but as he got older he seems to enjoy his guitar much more.
Best guitarists in terms of lead guitar: Chris Cheney
However, for overall general awesomeness my favourite guitarists are Matt Bellamy (muse) and Johnny Greenwood (radiohead), for their use of effects.
Oh and Don Ross (acoustic solo) is amazing as well.
What guitars do you guys use? My acoustic is a Maton ECW80C, and electric is a Schecter C-1 classic.
