You definitely want to do both & ideally much more. But yet again, even even if mask provided zero protection, as long as it reduces spread from asymptomatic carriers, it is a big win. But for that everyone needs to wear them - which is happening here in Czech republic. Just today a went for a walk through the second largest Czech city. The weather was nice and there were people in the streets, though a lot less than normally, with the usually crowded spots totally empty due to all the restaurants still being closed. To cut things short, the number of people without mask I saw during this hour and a half walk that were not wearing a mask ? 1
