I like G10 and Micarta and both are great for knife handles. What I like about micarta is the ability to use paper, linen, canvas, burlap, etc. for the layers and for adding texture. That can't be done with G10. I also like Carbon Fiber handles for folders...don't see it used much on fixed blades though. Any of the 3 can be roughed up enough to make them grippy. My CF Military is the grippiest CF I have ever handled. You can do the same with G10 and micarta. I agree, that it boils down to looks and feel and personal preference. I enjoy owning all 3. I have made custom knife handles out of black canvas micarta, and once polished, it looks exactly like carbon fiber. the finish put on these materials has a lot to do with both their looks and their feel.
