From my experience, the finish is a little nicer, and its a little easier to get good boning. (deep lines) I havent heard on price yet. But I would think they have to be at least similar price.
Oh, one other thing...you can get Conceal X in cammo. The color actually molded into the plastic. This is not so with Kydex, it has to be painted on.
Hope that helps, if anyone else knows more than me feel free!
