HTML >> Flash. Personally, I absolutely LOATHE flash/flex only sites. They behave horribly on the usability side, lack simple stuff like 'back button' and text sizing, and they task/heat up the CPU like you wouldn't believe (especially on a Mac). Flash has a purpose on the web... you can use it for various widgets that are impossible to do in HTML (say, recording and playing video and playing back animations and audio). But I'd never use it as a general presentation layer.
