My working theory is it's all to do with screen smoothness. My reasoning...
I've noted a lot in recent years that whenever I have a hire car (a lot), whatever it is from a cheap as possible micro box which must have the cheapest possible wipers, to a half decent Audi A4 type of thing with posh aero blades, they all have perfect silent wiper performance.
My own car, however, is often really noisy whatever price of blades I try. It performs best after a good clean and screen polish, and best of all after I clayed the screen.
My theory is a new screen is perfectly smooth and defect free and this makes wiper performance great whatever the blade. My 60,000-mile screen is, on a micro scale, pitted and scratched to buggery and rough as old leather. I reckon this leads to poor performance and shorter life of any blades.
I have seen the same with RainX - on my car its meh as described above, but on a new car I've seen it amazingly effective.
I'm gonna put this to the test soon as I have gotten hold of a DA for polishing the body and also got some ceri glass and glass pads. I'll restore my screen to like-new and hopefully see wipers performing awesomely.
That's the plan anyway
