Rhino Liner (and competition) doesn't hold up well over time, either. It is not UV resistant so will fade and does come off over time with wear. You can always touch it up, but if you've ever used the stuff before you probably wouldn't be looking forward to cracking it back open.
Line-X is a much better solution that is generally warrantied and has UV resistant variants. However it is only installed by licensed outfits so you'll be charged labor and all. I once got a quote from a place around the corner about if I removed absolutely everything I could myself less what I needed in order to drive it over to them and it was still north of $800 as I recall (this shop said they don't like working on Jeeps, that was when I had my 2-door JK for what it's worth).
For the time, money and results you get with Rhino Line I'd just as soon get BedRug. As mentioned before it's synthetic, so it is tough, which is why people like Rhino Line in the first place. Plus it's not a pain to install, it's easy, and mess free and doesn't require you to tear the whole tub apart to put it in.
