I have the industrial epoxy on my shop floor. It's very good but is not as bulletproof as claimed. It was not hard to apply, dries without nasty fumes in about 20 hours and it looked like a showroom floor for the first few months. The coating is about 1/32" thick and very tough but, it will chip if you drop something like a pipe wrench etc. I'd recommend using the sand to give it some tooth. Even with the sand, it can be slippery when wet. I also put the color speckles in it and think it looks good -it also keeps the floor from looking dirty all the time. I personally did not have trouble with dropping things and not being able to find it -but everyone's eyes are different...
I'm basically satisfied and it's way tougher than industrial paint but, in the high traffic areas and where I stand on swarf, it is starting to wear down. Normal paint would be gone by now -for sure. In a couple years, I will need a re-coat at least in some areas. I feel it's a good choice but, if I had a new shop with a flat floor in good shape, I'd go with industrial tiles of some sort provided the costs were reasonable -otherwise, I do the epoxy again but put two coats down in the high traffic areas on the first application. The low traffic areas look brand new.
BTW, if you search for Epoxy Floor Paint on the internet, you'll find much better/cheaper products than what's available at Lowes and Home Depot.

EDIT: BTW, the fumes were not bad at all really -much less bothersome than normal latex and by far easier going than oil-based paint.
