I'm not a fan of the rubber ones. They slide around when you load stuff that is heavy and you have to slide it in, like a snowmobile etc. Also found them to be slippery when they get snow or water under them. My brother had one and most of the time it was bunched up at the front of the box because when you loaded something it would get pushed up there. Unless what the others are talking about is something different from what I'm thinking of. The plastic liners are just plain slippery but do protect the box but also keep moisture between it and the box which will cause rust issues. Spray in is probably the best. If I'm not mistaken there is a product out now that you can apply yourself, not sure about the quality though.
