Which Wipers are Better?

Automobile Wipers: Some makes (M-B, Buick) have wipers that turn 180 degrees out of phase-, while the majority of cars use wipers that turn in phase-left and right blades move the same way-are the M-B style wipers any better? And dashboard guage illumination: BMW and Pontiac use red illumination at night-does this preserve your night vision better? Or is this a gimmick?
