I would definitely go with the spray in. I have had multiple trucks with Rhino, Line-X and drop in.

I HATE drop in's. They trap moisture/dirt etc under the bed, and everything slides around on the hard plastic. (Although there are some new drop in's that use a rubber base).

Rhino is good for something that is garage kept, or underneath a tonneau/ camper shell. They are much grippier, good looking and somewhat durable, but are susceptible to tearing and peeling with rough loads as well as chalking with sun exposure.

Line-X is MUCH more durable than Rhino, but at the expense of having a little less grip (Still 100x better than most drop in's with grip). There is NO fade with the sun, and it is about impossible to scrape off. I solved the grip problem by throwing a cheap rubber bed mat over it, although I love pulling the bed mat up and having the beautiful glittering black bed underneath. I have loaded many heavy loads with the forklift scraping against the Line-X with absolutely no problems. Also Line-X can alter the texture of the spray to suit your needs. My bed area was sprayed with a real course texture to prevent sliding, while the tailgate was sprayed with a smoother texture so it will not pick clothes while sitting on the tailgate.
