Plain edges look better to me each day, but I have to admit that the CS serrations not only make many cutting jobs easy, they're easy to sharpen. But like I said earlier, not all serrations are the same. Course serrations don't cut rope better, they cut it worse. They only help if you need to cut down a small branch or fibrous plant. The CS serrations actually cut paper straight and maintain their edges for phenomenally long times. I suspect they'd outlast a plain edge made of S30V or some other super steel. When I do need to resharpen them, it takes me less than 20 minutes and I can do it while I watch TV.
The finer the serrations, the better. I do love the way a few swipes across some ceramic stones will sharpen an AUS8 plain edge knife. Putting a good edge on a super steel takes much more time and effort. Me no like.
