There shouldn't be a debate about it in the first place. If you want an even higher chance of not dying if you manage to catch the virus, get the vaccine. If you care about reducing the spread, wear the mask. I don't see why either of these things need to be mandated as they sound like pretty clear cut personal decisions in my eyes but I digress.
What I am seeing are a lot of people that conflate wearing a mask to being protected from the virus' side effects, or that getting the vaccine makes it impossible for them to transmit, and that they are morally/ethically superior to those who take neither of these decisions.
