Sikorsky...afaik Polyaspartic is more durable than epoxy for scuffing and scratches ...and is used in high traffic commercial buildings like Costco, supermarkets etc. It's a thinner coating but may require professional application with proper equipment as it cures as fast as 10-15 minutes - so it can trap air bubbles and not cure properly if not applied properly. It also is more expensive than Epoxy. Polyaspartic also can be more slippery when wet, so additives are needed if the floor will get wet (sand/grit)
Epoxy is like it implies....2 part (catalyst and resin) that cures over time much like epoxy glue. Easier to apply but still requires a rough surface to adhere properly, so may require grinding or shot peening to reduce lift and peeling. Both available through all commercial coating companies... (I use Brock White out of Burnaby)
I'm researching Polyaspartic cost material wise vs epoxy, but I'm trying to determine how much more difficult it is to apply. All I know is Polyaspartic is extremely scuff resistant, chemical resistant and pretty much is usable next day.
Epoxy you have to let cure, so it can be up to a week depending on the humidity and how you mix it. (that's my only issue if I don't coat my garage and shop floor after we pour next week....as I'll have to remove all my equipment (3 hoists) and heavy shop equipment if I wish to grind and coat later on. I can likely place items onto the concrete within a few days even as wet as it is in town this week.....but to epoxy coat - I may have to wait substantially longer before I grind and then lay epoxy and then wait for it to cure. (we are in a time-sensitive reno stage where I don't have the luxury of waiting for weeks before I can move in)
The biggest concern I know as far as epoxy is you do have to thoroughly clean and roughen the surface you are applying to - even fresh concrete as it needs an aggressive surface to bite to. Once it's down, it's extremely durable..... (I had it in my shop in Burnaby for 12 years and it never peeled or chipped) I did have a small amount of sand sprinkled on top of my epoxy to reduce any slipperyness.
All those that run Racedeck and others on RRAX (race forum I frequent ) all voice the same concerns about jacks, dollies and hoists don't roll the greatest over it.
With epoxy in my old shop I regularly used GoJack dollies and floor jacks to move race cars around with zero issues or scarring. Very easy to clean (mop and bucket for any major spills) and power blower or broom to clean up loose dirt.
Racedeck you have to lift and remove if you spill any oil or solvents and then pressure/wash before you re-install.
