The cool thing about Evangelion is that you don't have to choose a favorite. It's a very rare opportunity to see how a single story can be told in different ways for different times and different meanings. All of the endings are good, in my opinion.

Personally, I don't think the original ending is in line with the pessimistic tones of the original run. I find it kind of strange that shinji self actualizes at the end when there's really no indication as to why that would happen. Because of this, I think EoE caps off the the original run perfectly.

However, Rebuild presents a very different set of events, and the optimistic self actualization ending makes a lot of sense. It decided to retroactively make the original ending appropriate.

So... They're all great
