This is a tough one, because there're so many different reactions to wipers on the 4runner.
Stock-
These fit well, and wipe well. I ski a lot in the winter, and these also hold snow well and ice up in the frame, which means they stop wiping well. But if it's just rain you're lookin' at, these work just fine.
Rain-X Latitudes-
"Frameless" design which looks sexy and puts a Rain-X sheen on your windshield when you use the wipers. These actually work pretty well, but many members report that the top of the windshield does not make contact with the wiper (or vice versa, rather). This is a minor annoyance, but it's still there. Some guys go shorter than the recommended length on the driver wiper, some don't care. Be careful setting your wipers down, so as not to slam them (accidentally). I broke the bracket on mine (kinda cheesy).
Bosch Icons-
These are just like the Rain-X above, but with an attachment bracket that is sleeker, and without the Rain-X protection applied to the windshield while wiping. They have the same issues as the above Rain-X wipers too (windshield contact at top-wipe). These brackets are not quite as fragile as the Rain-X's...
I hope this helps a little...
