If you judge this debate purely on the "how to debate on tv" standards, McCain did poorly. He never looks at Obama. He giggles nervously and his eyes dart away, and at the precise moments when Obama is landing a punch--when McCain should be standing tall and looking elegant or bemused, as JFK or Clinton would have--his eyes blink and he looks down nervously and away, like he's hiding something, just like Nixon used to!

Basically, here it is: With the sound down, Obama took it, hands down.

My main stylistic impression was that Obama was crisper than usual, sharper, and more aggressive than in his debates with Clinton.
