Best floor mats and cargo liners for a new BMW X5?

I just took delivery of my new BMW X5 last week, and I’m absolutely in love with the interior. However, with winter approaching and my kids constantly tracking in dirt and mud, I know those factory carpet mats aren't going to survive very long. I want to protect the floors and the trunk area before things get messy, but I'm torn on which brand to choose.

I’ve looked at the OEM BMW all-weather mats, but I've heard they might not offer as much side-wall coverage as some of the aftermarket options like TuxMat or WeatherTech. For the cargo liner, I definitely need something with a raised lip because we often haul groceries and sports gear that can occasionally leak. My main concern is finding a set that doesn't look too 'industrial'—it really needs to complement the premium feel of the X5 cabin without looking like a work truck.

Has anyone here tried the 3D MAXpider mats? I’ve seen some photos online and they look pretty sleek, but I’m curious about how they hold up over time. If you have an X5, what are you currently using to keep your floors pristine? Are you happy with the fitment and how they look after a few months of use?
