Different professors will warrant different study aides. I know some people who used Chimerinski for Con (which is VERY in depth and longer than the textbook) and the prof liked the E&E way (short and concise), so I would just ask around the 2Ls that had the prof before you. Also, find one that works for you and fits your learning style. Some have flow charts and all sorts of crap in them and then some it is just the rule and nothing but the rule, so it's just a matter of personal preference.
