Here in the Northwest, we get lots of rain, so I have tried a lot of different combos. The best bang for buck is a set of Teflon refills ($8 each at CutRate Auto). Then you use "No Touch Window Stripper" on the glass to get it clean, followed by Rain-X to reduce surface tension.
When you're done you'll wonder why people use wipers on the freeway 'cause you probably won't need to!!
