Tried many kinds of pads and rotors over the years in many different cars, as have my family and friends.
The only option that always delivers is OE.
When aftermarket parts are cheaper than OE, they always seem to have some kind of downside. I've seen aftermarket parts that are comparable overall to OE, but they're the same price or more and usually still have some downsides, so I almost never see the point. I don't think I've ever seen anything in the aftermarket that was all upside, barring certain high-end conversion kits ($$$).
Sometimes you're forced to go aftermarket because your use cases is very different from what the brakes were specced for (e.g. extended track use). Or you have a specific performance preference that's so strong that big downsides are acceptable (e.g. you'll accept noise and dust if it means more bite). But even in cases like those, you're not getting something that's better than OE; you're accepting something that's worse overall because that's the only way to get what you want.
