Is this just a "would you rather" hypothetical game or a serious question? You posted it in Planning, so I am not sure. I guess, in either case, I would choose to be the only one without makeup because I can't imagine telling all my guests they couldn't wear makeup.
Why would you ask your guests to come makeup free? If someone asked me to come to their wedding without makeup, I would decline the invitation. You don't get to tell your guests what to wear or whether or not they get to wear makeup.
