The best refills for the factory wipers are made by Lexor. They seem to be hard to find at the moment though. Lexor is one of the premium brands for Pylon. The Pylon refills are most certainly cheaper in every respect and in my mind unsatisfactory.
The Lexor blades are also a premium blade. I much prefer them to Bosch. They are also hard to find at the moment.
Another of Pylon's premium brands is Michelin wiper blades. They are available at Target and Wal Mart. It looks like the Target ones are a different model. The Target ones are among the most expensive blades I have bought, but they are worth it. The Wal Mart ones have different labeling and every indication from the Pylon web site is that they are different. They are about half the price of the Target ones. I'm probably going to try the Wal Mart ones the next time I buy blades unless I can find a local source for Lexor refills.
