Personally my favourite version has become the one at Auto in 2002. I love that Neu/Krautrock motorik vibe they give it, like an unstoppable robotik machine.
Common People has been upsetting me this Summer. For that, Disco 2000 and 'First Time' you have to brace yourself and hold on for dear life whilst everyone around you tries to kill you. My favourite bits of Common People are the quiet bits. There are less beatings there.
