I have LineX and I agree that things slide around on it. I can't compare it to Rhino since I have never seen it up close. I bought an indoor/outdoor rug and cut it to fit the truck bed. It is great because it holds things and then I can yank it out, shake it and all the debrie is out of the truck bed. When it is wet, it does take a long time to dry but that's not a problem if you have a spray in
liner below it (i.e. it won't cause any rust). I have a new Tundra on order and was slightly currious about those new rug liners that are custom fit and even go up the walls. I wonder if they would go over the spray in. My indoor/outdoor carpet saves my knees when crawling around on it and I would expect these rug liners would be even better on this depending on the material and thickness. Still, I will probably go with LineX again and the indoor/outdoor rug.
