I was offered epoxy garage flooring instead of rubber flooring because it's durable and seems quite cost-effective.

Has anyone done this before?

Yes, I've seen many cases where people chose epoxy flooring over rubber. They are indeed durable and easier to clean, especially in a garage, but it's important to ensure the subfloor is properly prepared, otherwise cracks or peeling may occur over time.

Epoxy provides a very durable coating. It can withstand vehicles, tools and impacts, and is virtually impervious to oil and chemicals, which is a huge plus for a garage. It's also easy to clean and visually, it looks much more expensive than regular concrete.
