I like the Weathertech mat because you can still use the rubber straps in the floor. There are holes you can cut if desired, and it still remains mostly waterproof. The may does curl a little bit towards the latch area, but its fine.
Went with Weathertec nice tight fit, but very thin. Good for capturing spills, but don't think it will help for any real sound dampening.
Wish the Maxpider 3d made a matching cargo mat.
