Both the cementitious urethane system and a specific line of modified polyaspartic will be nearly identically effective at keeping the surface of the coating sterile. From there it would depend on other conditions in your environment on whether you'd decide on one or the other. In either case you'll have a sterile floor ideally suited to maintaining top health standards. Both products have been approved by the FDA for use in commercial and industrial kitchen floors. For less physical and thermal shock demanding floors we'd recommend the polyaspartic. In settings like dispensary grow facilities where preventing plant pathogen growth is essential, yet the floors dont undergo as much stress as say an industrial food production plant, we'd recommend the polyaspartic. For surgery rooms in hospitals, it is almost a coin flip, because if there is the likelyhood of sharp and possibly heavy instruments being dropped onto the floor, as well as stretchers and carts with abrasive wheels wearing on the anti-microbial floor coating. The cementitious urethane is easier to slope down into a drain if this is an issue. Depending also on the amount of abuse and traffic your floor will experience you may want to opt for the more affordable polyaspartic and have us re-apply every four years or so as opposed to having a floor with a 20 year warranty right from the get go.
