Line-x, Rhino or manufacturer spray bed liner?

Have to say I have found just the opposite from Travelnutz. The Line-X is so tough the use it to fortify buildings and bunkers against bomb blasts. http://www.linex.com/pages/2010/military/

Only time I gouged my Line-X is when I turn the tines on when loading the rototiller so no their fault. My cousin had the Rhino liner and we took chunks out of his liner shoveling dirt out of the bed. Never had done that with mine.
