I've had a lot of hit and miss experience with aftermarket blades. The vehicle in question makes a huge difference, but in general the best I've found are these:
They are a hybrid between a beam type blade and a tension type blade. The issue with beam blades are that they will miss the bottom edge on a more curved windshield, but they work well on flatter windshields.
These seem to have the benefits of the beam blade (more consistent pressure across the blade) yet still conform well to the windshield when it curves.
Lexus use a similar style blade OEM now (not as nice, has a plastic cover instead of metal) so I've left the OEMs on my new Lexus (Had these PIAA ones on the '03 I had before) but am planning on picking up a new set of these for the Jeep.
