To each their own, I suppose. Mine are direct from Lloyds Mats, not Cruiser Corp, so I can't confirm that Cruiser Corp gets them from Lloyds. They just look similar... I'm happy with my Lloyds, though, except I didn't love the "cream" color I chose for my 60. I thought it was going to be more of a darker desert tan.
Mine don't slide or move around
at all. I have them in my daily driver pickup, as well, and I have no issues with them moving around. In fact, after installation I have not had to readjust them a single time. The backing has little spikes that grip my carpet just fine and it came with a couple hooks for the driver's side.
I'm not sure what "loud underfoot" means, but mine don't make any noise when driving, nor do they make any noise when I get in and out of the truck, nor do they make any noise when I drag my boots/shoes across them... They just don't make any noise...
They are simply a bulk sheet of rubber that is cut by the manufacturer to fit a specific vehicle--but the cuts are far from rough or look like they were cut with dull scissors. All the edges are clean and straight... Are they fancy? Not at all. But my daily driver and my Land Cruisers aren't show trucks. They're just made to be used and I need something practical that can withstand sand/dirt/rain/snow/etc. Carpet mats are a no go. The Lloyds work great for my needs and the price is right. They're a good middle ground between the cheapo cut to fit mats and the overpriced Husky/Weathertech.
YMMV.
