I have knives by both Spyderco and Bark River that utilise G10. I have RAT cutlery knives with Micarta. I like them both but I prefer G10. G10 seems to be tougher and better in wet/cold conditions. Its just my personal opinion though!
I take the point that there is a difference between good G10 and crappy G10 but both the Spyderco and Barkie are very good.

I love the Resiprene C handle on my scrapper, great handle.
