I am 5'9" and have ridden an AT with both screens.
Standard screen - perfect for me. No buffeting and good weather protection.
Touring screen - top of screen cut my line of sight. Good weather protection, but buffeting from the sides. Vibrated a fair bit too.
I think the touring screen was an after thought by Honda. It does not look as good as standard and probably did not spend much time in the wind tunnel.
Standard screen for me.
