Have used both for my previous ride and now choose to use 3D maxpider. For me , the custom fit (does not move around at all), easy maintenance (vacuum with occasional wash and dry) and the OEM look made Maxpider a simple choice for me. I personally do not find the 3M style mats not to be as aesthetically pleasing.
If you are planning to go the 3M style mats, my suggestion is to stick with the 3M brand. Quality of the other look alikes cannot match 3M and do not last as long. Tried almost every supplier of such mats.
Good luck with the search.
