I graduated a few years back and can say that, when compared to the Tempe campus, the West campus wins easily. The fewer students here makes it easier to pay attention in class, understand what's going on, and actually have a chance at asking questions to your professors. There is no worrying about the professor seeing you (compared to the 100 courses at the Main Campus). Overall, the smaller campus makes it a more personal experience. It was a nice place while it lasted.
