Bacteria has a much harder time growing on stainless steel than plastic. Unless you are going to clean the plastic feeder with a bleach solution fairly frequently, you cat will be getting bacteria transferred from the edge of the bowl to the cat's chin.
My cats usually jam their whole faces in the food, so I dont have an issue with that, but we did change from a plastic fountain to a metal one, and their chins got much cleaner. It is possible your cat's issue is with the water and not the food delivery.
