"Amazingness" is a pretty good term for it. I don't like this Gould version, and i'm sure pianistimo can play it better. The speed and technique are amazing, of course, but it sounds like Mozart as interpreted by circus clowns.
Just for fun, I attached my recording of the 3rd movement, which is admittedly imperfect but at a tempo I much prefer. I recorded this a few years ago as an application to an amateur piano concert, and I had not polished it that much--and my dog barked in the middle. But hey, it's all for fun!

P.S. Now, pianistimo, it's your thread, c'mon, let's hear yours!
