What's CFMicarta. Was if Micarta with a CF inlay, or did you mean Canvas Micarta.
Micarta grips better(esp when wet), and is lighter. My favorite material. I'm not a fan of G10 on a fixed blade, but don't mind it on some folders.
If given the choice I go with micarta, but G10 gives you better color if that matters to you. G10 is also a little tougher, but either is plenty tough enough.
