Every dealership or industrial shop I worked in had coated floors and they held up very well. Im talking about these floors takings a ton of abuse! I have seen a transmission fall 3 feet onto the ground and put a tiny chip. Dropping control arms and ball joints etc, maybe scratch.
Now, on the other hand, I worked in a tire shop that had a low grade/low cost floor and that stuff sucked. stay wet too long and it would peel or come up. Much of the durability goes into how you prep it. Does it look nice, yes. Is it better than bare concrete, depends. If you are going to weld for weeks at a time and have a light colored floor, you will then have a light colored floor with a black/brown spatter stain of burn marks. If you spill oil often, you wipe it up and no harm no foul-not like concrete which is virtually an instant stain and requires some scrubbing with chemicals
