I watched a couple of videos on how to choose a helmet. Very helpful!
I tried on dozens of helmets at a motorcycle super store, on 3 different days.
I settled on a HJC modular helmet ('flip-up' full face helmet) which had the only size & inner shape to fit my head and my chin (!) , and permitted me to keep my glasses on while putting on the helmet.
I think there is little argument that full face helmets are the safest.....(ever see a racer in any other kind?)
If you want to look cool, buy a nice 1/2 or 3/4 helmet to wear while you watch truck racing on TV!
Or wear a ball cap backwards , flip flops, Nike shorts and a nice Tee on your scooter - the commercial skin graft repositories and reconstructive surgeons love that look.
Full face helemets are the best thing for riding in traffic on 2 wheels.
