For obvious reasons...
I'll put my candidate:
Schumacher Barcelona 1996, extended highlights here:
Qualified 3rd at +0.9s in a Ferrari that later would become a B spec, since everyone started using high noses but Ferrari was late on that. The race was a complete downpour on full wets of the kind that we wouldn't race with today. And another thing that didn't happen that often back then was safety cars. Eventually only 6 cars finished the race, everyone else basically spun off or broke their cars.
That Ferrari wasn't just a bad car in its own right, the Williams that year was absolutely one of the most dominant cars of all time winning 12 of 16 races with 6 1-2 finishes. Aside from the italian GP, if at least 1 Williams finished, there would be one on the podium.
Eddie Irvine, Schumacher team mate, finished the season 11th in the WDC with a slew of retirements, and even when he finished it was bad.
Schumacher had a clutch issue on start that made him lose 3 places, making him 6th before T1.
Race progressed with Michael lapping up to 4s/lap faster than the 3 following him (Villeneuve, Berger and Alesi).
Lapped everyone except the podium finishers who anyway got gapped 45s from Michael.
To me this is easily in the top 2-3 drives of all time.
