Most importantly is making sure you have the tools that match your vehicle rather than a "good tool set." For example on my 2000 Ford Super Duty I need 1/2, 3/8, and 1/4" drives and a 24mm or 15/16" socket in case I lose an injector (which is more than possible), as well as a 10mm deep socket in 1/4" drive and a magnet stick. Unfortunately this takes time wrenching on your certain vehicle so I would say ask this question in your section (Jeep, Toyota, or whatever) rather than a general 'recovery and tools' section for the best answer. Otherwise anything that 'works and won't break' is usually fine.
