I found some of the E&Es helpful but not all. Definitely think Glannon's Torts and Civ Pro were great. I agree that the best thing, other than preparing your own outline, is to make friends with a 2L or 3L who had the same prof then supplement your outline with theirs. Commercial outlines can be good for this too, but just not as good. I also agree with getting something keyed to your casebook or at least written by the same author (ex. Dukeminier is popular casebook among Property profs and he also authored several study guides). Its important to find what works best for you. That's why I recommend trying a few different ones out (there's a zillion out there besides Gilbert and Emanuel, such as Blonds, the Lexis Understanding Series, Crunchtime, Law in a Flash, which is especially good for short hypos, Q&A series or Exam Pro (good for exam prep) and for briefs the High Court Case Summaries or Casenote or Legalines series. And that's just the tip of the iceberg.
