I missed an Eva v Guilty Crown discussion?
They are hard to compare, though I would probably put Eva a bit more on top of Guilty Crown. Guilty Crown out did it in the character bonds and interactions department, friendship, and music, but Eva's plot ultimately affected things that were larger than life altering and affecting both time and space, mech designs trumped those of the Endlaves, and I think its whole premise of NERV, Instrumentality, and x Impact was a bit more well done and intricate than say Void Genome and Daath. I think more is had out of rewatching that more than rewatching Guilty Crown. Shinji and Shou are ultimately the same character types that I love so I think neither exceeds the other. However, I would put Shou on a say top ten characters ever list, while Shinji would be somewhere around 11 or so, though his plug suit design is nice. At the end of the day, both are anime I would have on a list for the most definitive anime of their respective decades/generations.
Honestly, I'm wondering what the inspiration for Guilty Crown was or something like that. I know there was an interview a long while back where they mentioned something about CG. Meh... idk...
