Having just taken the real boards, I do not think Crunch Time is an equal substitute for Hippo. Hippo is more basic compared to Rosh or Peer and might be better for interns. I started listening to Crunch Time during my commute and it just takes too long. I have a short attention span and am not an auditory learner so maybe that's why I didn't like it as much. For 2nd and 3rd years, I'd recommend doing Rosh at least once to be golden for inservice. Interns would benefit from doing the videos to actually establish that knowledge base and doing the Hippo question bank. YMMV.
