Test ride them both... and decide which suits YOU...
for ME.... the bat wing is too "in your face".... I like the spread out feeling of the sharknose.
except for the fairing.... there's no other difference in the two.
Either bike, you may find yourself tweeking on windshields/handlebars/seats to get it "right" (for you)
Protection? I think it's a toss up.... I'm as wet, or as dry, as my buddy on his ULTRA (EG) so I can't say ...
Folks claim, the batwing, will transmit wind shifts through the handlebars, while a shark, will not....
both great bikes.... but there's only ONE bike for you....and that's the one YOU select
