I thought that it was accepted that the main benefit was in protecting other people. I wear a mask and a transparent face shield together. I believe that this combination offers me some protection and a lot of protection for people near me, so it seems like an obvious thing to do.
BTW, I find cloth masks not so comfortable, but the plastic face shield is no real additional discomfort at all.
