Some people think G10 looks and feels cheap. It's all subjective. Performance, however, is objective. FRN performs consistently. There's really no way to argue with that.
Personally, I think that some of the aluminum and stainless handles on the market look cheaper than their FRN counterparts. Improvements in texture also have the corollary benefit of making them look fancier, IMO. If a great deal of effort was put into making them look more expensive, it would certainly be possible. But would there really be a point to it?
I still prefer G10 and Micarta in the hand, but will never snub my nose at FRN.
