What I think is better is going to be pretty worthless for you. The E&E is completely different than the outlines, and as for the outlines, they're organized a bit differently, and have slightly different formats.
I'll take an E&E over a generic commercial outline any day, as I find the questions/answers helpful. I don't like any of the commercial outlines.
If you're a 1L, asking this question NOW, it may be a little late in the game to even be figuring out the differences. I suggest you go to your library or bookstore and take 10-15 minutes and flip through the outlines the E&E to see which is best suited to your learning style.
