Anyone have any experience with the Weathertech vs. BMW OEM floorliners?

The Weathertech ones look like they cover more, with the rear being a once piece that covers the small center hump, and the fronts looking as if they go higher onto the center hump, but I suspect the BMW OEM ones might fit better. They look like they both might be sourced from Weathertech, or BMW has copied the rib style, etc.

Winter is coming and with a new X5 that is Sand Beige, I think I need more than floor mats.
