By six-string do you mean acoustic or electric. I find it a crucial difference as there are two different styles (basically.)

I find acoustic (especially Martin or Taylor) to be especially fun. The strings ring out perfectly (with a little tasteful rattle) and the high strings sound very beautiful with six-string cords.

Electric, although is my forte. While I play mainly metal, I think I have a very diverse range of styles. My main focus now is the ability to solo.
