I have both in my bag, and the 6D is the one I pull out more often for video. Generally they're very similar aesthetically until you need higher ISO levels, at which point the 6D is far and away the better camera. 6D also can auto-split files up to 30min of recording, while the 5D stops at the 4GB mark (around 12 minutes). The only consideration for getting the 5DMkII over the 6D (for video) would be if you need Magic Lantern functionality, which is available on the MkII but not on the 6D (yet).
