I wear a modular full face until it gets too hot and humid and then switch to a 3/4. I also wear a textile, mesh jacket with body armor and Draggin' jeans with Kevlar. Doesn't matter much what I'm wearing - my bike makes me look cool no matter what!
Any time I'm on the highway (or traveling long distance) I wear a full face. So much more protection, helps with wind noise, and like others have mentioned, in the rain they are so much better.
