As a 1L, I remember finding the Bluebook initially difficult to use for a bunch of reasons, but especially because Bluebook has two sets of rules depending on whether you are writing for law review or for work. The ALWD manual has just one set of rules for everybody. Simple. If you need to cite a case, then flip to the sub-chapter titled "case citations" and find everything you need on the subject right there. Unlike the Bluebook, this is divided into normal chapters (like most other textbooks), so you don't have to waste time flipping back and forth looking for stuff. Again, simple and easy. Unlike the Bluebook, you don't waste a bunch of time "learning" how to use this because it is intuitive.
