I think the inlays are great, but being a minimalist, I think I prefer the plain scales. I had a small micarta insingo, and it felt really good in my large hands which was a surprise to me. The micarta definitely adds a bit of thickness to the grip which fills out nicely along with the pocket clip when in my hand. The micarta inlays also remove some of the weight of the all titanium scales which, for most knife users, is probably a desirable thing. I prefer a little bit of heft to my pocket knives which is one reason why I like the plain jane scales more than the inlays.
The main reason why I am not attracted to the inlays is because CRK uses a super strong double sided M3 type tape to glue the inlays into the scale. I am 100% positive that they will never wear out or fall off from heavy use, and I have never heard of anyone having a problem with that. If the tape ever did fail, I'm sure CRK would repair or replace the knife under warranty. For me, it is just the idea of there being double sided industrial strength glue-tape within my Sebenza that putts me off to it. As a minimalist, I like the use of less materials, and on a finely made knife like the sebenza, this means a lot to me. For myself, less usually equates to more.
