I have a Rhino liner in my truck. Its been great, nothing slides on it, and you just hose it out to clean it. I've never had a Line-X liner before, but I've also heard good things about them. About the only bad thing I can say about the Rhino liner, is that it fades after a year or so. Nothing major, just looks a little dull. Whichever you choose, just make sure the installer does the prep correctly, and make sure they take out your bed bolts,(not just spray over them), makes it a whole lot easier if you were to ever remove your bed for any reason.
