Eva, while possibly being the deepest anime out there, isn't nearly as good a show as Bebop. Cowboy Bebop has far superior characters, animation, and fleshes out the story extremely well throughout the show. Even though the main antagonist is only present in 5 episodes, you feel extremely strongly for Spike by the time you finish the series. Plus Eva has waaaay too much angst. It might be a masterpiece, but the last eight or so episodes aren't any fun at all.
