I own both mats for a number of cars.

I LOVE the all-weather mats (the $70 ones in your post). They are very high-quality mat made of a heavy rubber. I typically use these in my cars in the spring and late fall, when there is a lot of rain and my shoes may get a little muddy (I prefer carpets in the summer).

I have more mixed feelings about the floor liners. The Weathertechs were one of the first on the market, and it was in my view a revolutionary product for those of us in a winter climate. As the previous replies said, they are designed to hold more water in and go partially up the tunnel; but they are slippery, cheap-feeling, and typically have a major design defect or two - (1) they always only go half-way up the dead pedal, so your left shoe dumps all the snow BEHIND the mat, and (2) in an effort to be able to slide the seat over it, many of the mats have too-shallow a back ridge on them, so rather than containing any melt they channel it under the seat as soon as you accelerate. This problem does vary from car to car, but both the liners for my Cadillac CTS and my Chrysler 300 have the same issues.

The Husky liners I bought (to replace the WT) for the 300 aren't quite as long and don't extend under the seat, but have a taller rear ridge to contain the liquid and have a higher dead-pedal cover.

If you don't use your Porsche in the winter (or where there is a lot of snow) I would recommend the first ones (all-weather mats) hands down, I use them in my 997.2.
