My opinion is rather the mat must be efficient in traping dirt/stone etc because all this gets sucked back into your aircond, particularly the front passanger mats.

in terms of looks - original carpet is always the preferred choice but does not trap dirt well, if you clean it very often then no problem
if lazy then maybe dodo because it can trap dirt below (2nd layer), or the maggi mee type rubber.
trapo concept is good, but need to maintain regularly too otherwise defeat the purpose

most important - need to be hard working to clean the mats.

original carpet mat is still be best
