Line-X is a harder compound that Rhino. You won't be able to scratch the Line-X as easy, but since it is so hard it can chip easier. Line-X tends to be more brittle, Rhino is a softer, rubber-like compound. I have a Rhino, and I looked hard at the Line-X. The Rhino grips stuff better, things don't slide around as much. Basically, it all comes down to two things: What you like and how talened the guy running the gun is. No matter which product you choose, the actual bedliner you drive away with is only as good as the guy spraying it. Go to each shop, talk to the guy who shoots it, and look at some of his work. I have seen good and bad examples of both Rhino and Line-X installs. Do some homework, and consider not only the product (because they are both good) but the talent installing it. The only thing I have noticed about Rhino is that if you drag a lot of heavy things in and out of your truck, the abrasion will wear on the Rhino more than a Line-X. Conversely, the Rhino will take a hit and be fine, whereas the Line-X is more likely to chip and separate from the metal when dented. Good luck with your decision.
