The BEST one? That's a tall order, I go with fit. I love my WRSI, it seems there's no way for it to roll back, if I have it buckled. A bit of a visor for sun too.
FWIW, On full face, I took an oar to the jaw this weekend, and thought out loud about a full face. A Class V veteran told me how he had an oar slide up and under a full face, and punted him off his boat. Now that I've given some thought about what an oar can/could do/go I doubt I'll be considering them one soon.
