As jacko15 said, website does a good job but since I have had both I'll give you my version.
Net, net, spend the coin and get the X-Act Contour's and don't look back! I had the regular Husky's in my '02 JGC Limited and while they wear like iron and keep all the gunk out of the carpets they are too slippery when wet, the edges curl over/inward eventually and they have a very low tread profile which means your shoe heal sits down in the melted muck. The X-Act Contours have all the benefits of the Weatherbeaters such as tray design to hold liquid, reverse/up-dimples for the carpet hooks so saltwater doesn't sneak past into carpet thus allowing you to easily empty the mat as the snow melts, complete coverage behind gas pedal and dead pedal plus it has a nice little overlap lip that goes across your entry sill. They also offer an awesome grippy, soft rubber compound construction to prevent slipping and they have a decently deep groove/tread design that helps keep shoe heals and pant cuff out of the slop. If snow, ice, salt and mud are the reasons you need floor mats then no other mat compares. The X-Act Contours are better than the Mopars, Rugged Ridge and WeatherTech's. But they do cost the most.
