Two different categories being discussed:
Full Face - Best
Modular - forget it even has a chin bar, its a 3/4 with a wind protector, none of them actually protect the chin like a real full face.
Really, once you get to try on all the ones your considering, I'm sure the right one will stand out in the fit.
If you're really concerned about the safest possible lid, look at the Bell Race Star and Pro Star or anyone that's developed equivalent multi-density foam interior where it can vary deflection based upon shock load, it's not a revolutionary idea, but they're the first I'm aware of to properly implement it in a production lid.
