I have a RhinoLiner. It has a rubbery texture and doesn't let the load slide
around in the bed easily. Good for preventing load shift when traveling but
not so good for sliding heavy things to the back of the bed for unloading.
Line-X is a harder surface that's a bit more slippery. Both brands seem to
be very durable. Personally, I think finding a good installer is more
important than which brand you get. My installer was a bit sloppy where the
liner was trimmed around the tailgate opening but it doesn't look bad enough
for me to take it back and have it fixed. Inspect your truck carefully for
overspray and other installation problems before you pay them.

I had Rhino liner in my 96 2500 and I have X-line in my 05 2500. I
would have to give the nod to X-line. It really makes a difference on
the installer. Make sure you get to look at some of their previous
work.
One other thing. Rhino liner is warranted by the installing dealer. If
they go out of business?????? X-line is a national warranty

Not sure if I have a preference, as I only have Line-X experience, but I
love my Line-X. Definitely no problems with it, and is still as good as
the day it got put on almost four years ago.

ive shopped for a bed liner for my truck since before i bought it. yesterday
i took it to line-x and had them install it. the main thing i looked at on
several occasions of visiting the dealerships of the various spray in liners
was the quality of the workmanship.

whoever you choose, i believe, they all have a quality product as far as the
materials used. the main differance between them is actually dealer to
dealer in the quality of installations.

my truck turned out beautiful! all the lines are straight, and i mean
straight edge straight, next to no overspray at the front wall to cab area.
but in my looking i seen several occasions of dealers that were nowhere near
as good and some that was ok. even within the same line of product.

ive rambled about this basically to say, take your time. visit the dealers
ask to see recent instalations they have done and inspect them closely.
choose the product and dealer you like best. thats what i did and am very
pleased.

also as others have mentioned check into the warranties. are they the
installing dealer only or national? i know line-x is national as was stated
by some others. but that was a last factor for me the install was main
priority.

good luck
