My experience is quite a bit out of date by this point (close to a decade ago now), but I recall Vandy really beat the **** out of you with regards to work hours. I had the PD send me a schedule for the month I interviewed. Assuming 0 minutes for signout, fellows still were coming up against 80hrs a week on the regular.
Back then, Duke similarly had bad hours (they were still doing 24hr calls), but I didn't interview there, so cannot say for certain.
I had an attending that trained at Stanford, and he loved it. However, he said that in some units, you'd be a consultant, and just ran the vent +/- pressors, with the primary team doing the rest of the work. Again, his experience would have been ten years ago, now.
