My .02 is that I'd love to have some sort of tile. It's a pain always having to worry about fluid spills and soaking them up so they don't stain the floor. Tiles just clean up so easily and they look great. I'm sure epoxy is similar in respect to clean up but the nice thing about tiles is that if you break one you can just replace it instead of having to fill that chip in your floor caused by a large falling metal object.
So, my vote is for some sort of tile and to get enough extras that you can replace anything that get's damaged in the future.
