I'll go against the grain and suggest porcelain tile. I've researched options on GarageJournal forum and selected the tile as the best one for me.
RaceDeck and Swisstrax were both the same cost per sqft as my tiles installed. What I didn't like about those options is the maintenance: having to either pull out the whole floor and clean the concrete once a year and I wanted to prevent deterioration of my concrete by having salt and water sit under the tile until I have a chance to pull them up and clean underneath.
After doing my rear brakes recently on another car, the clean up of dropped grease and sprayed FluidFilm was a wipe down of the tiles. In the past, I'd run for a can of brake cleaner before it would soak into the concrete - something RaceDeck tile wouldn't prevent. There are solid tiles too, which solve a lot of what I described, but
for me the porcelain outperformed those options.
