Line x, it looks good and holds up very well. My truck now has the factory 2010 ford liner and it looks more like my dad's rhino lining. My truck isn't worked that hard but my dads is and his liner is starting to peal and has lots of gouges in it.
I liked rhino lining when we had it in our old truck. Never had linex so I can't say about it but I liked that the rhino had flex to it and gripped things better. Nothing would slide around like it does in my truck with no lining at all.
