60D or T4i

So I need to purchase a Canon DSLR for another office. I know Nikon (our primary office set of cameras) Pentax (my camera of choice) and Sony, but not Canon. Well, the people in this office only want Canon, so I have to oblige.

I am sitting between getting the 60D and T4i. I think I am stuck between choosing between these two on two important issues - build strength versus video abilities. How much more durable is the 60D over its Rebel siblings, and how much does the T4i excel over others in the Canon family (including the T3i)? For those Canon users, which one would you get?

Camera will be primarily for stills, but will need to shoot video.
