I’ve owned the OEM and WeatherTech all-weather floor mats. The WeatherTech mats got returned almost immediately. They’re not a perfect fit, and have a hard plastic feel underfoot that’s quite unpleasant. We have them in many of our work vehicles at my office, and they all exhibit the same characteristics of poor fit and a hard plastic’y feel that I really dislike. This is across vehicles from multiple manufacturers in several different styles (i.e. trucks, SUVs, cars, vans, etc.).
The OEM mats, by comparison, fit perfectly, feel considerably more supple underfoot, are quite robust, and have stayed in ever since I installed them.
The Tuxmat offerings get a lot of love. I’ve never tried them, but I like the OEMs so much that I have zero inclination to bother with anything else.
