Line-x, Rhino or manufacturer spray bed liner?

Rhino hands down!

Far superior to Line X as Line X is very hard and everything slides around on it and it also chips very easily. Rhino doesn't promote sliding as it's softer, more flexible, and much tougher so it just doesn't chip. Seen so many Line X truck beds with chipped out gouges down the the metal. Especially in the colder or freezing climate regions. Something you'll very seldom see if ever with the more flexible Rhino liner coating.
