I would think that G-10 would outlast Micarta, particularly paper, the scales on my Hibben Dragon Claw for example, the pattern started to blur and shift after I started carrying it IWB, although they haven't swelled or anything, there was a definite effect from me sweating next to it all day, whereas the G10 on my EDC pocketknife only shows wear and tear from being dropped, a couple nicks here and there. Plastic is entirely sweatproof, whereas the Micarta probably isnt.
