A helmet is an individual thing so wear what you want. But one thing that has happened over the years is they realize the face can get messed up too so full face helmets evolved. Yes you will be more protected plain and simple. Now the real question is to you need it? For show purposes if you do that then a vintage is to way to go. But an afternoon on some fire road maybe a motocross style. It really is totally up to you though. Don't let anyone pressure you one way or the other.
