And all the baddest drummers use Paiste.
Bonham, Keith Moon, Phil Rudd, Marky Ramone, Alex Van Halen, Greg_L, just to name a few.
Hehe. That made me laugh.

Great drummers play great cymbals. Paiste, Zildjian, Sabian, PA Meinl: all great cymbal makers. Endorsements are secondary.
Someone made a great point earlier about Paiste's quality control. Zildjian and Sabian have it, too. I think the original spirit of the thread was to discuss consistency & quality among manufacturers... To that end, I think the blanket statement can be made that most major cymbal manufacturers have enough quality control in place to produce a consistent product among their pro-level model lines.
When I say "consistency", I'm talking about the quality of the product, the general response of the cymbal, and the types of tones you can expect.
My Zildjian Avedis crashes may have a slightly different pitch than your Avedis crashes of the same size and finish - because they're all lathed and finished by hand and that allows for variations - but they'll all have the same fundamental tones, and the quality will be consistent from cymbal to cymbal. Sabian's AA and HH lines would be the same situation.
If the specific... say, pitch... is what you're after, there's no substitute for a trip to your local percussion shop (or to a cymbal factory if you can arrange it) to test specific cymbals themselves.
