As far as Evangelion goes, I think the original series is the best of all of them, sure the Rebuild movies are more polished and not as dated, but for its time it was an amazing anime that had a bit more story to it than just sensless robot violence.

SDF Macross is also good, again its dated now but im my opinion it mops the floor with Macross Frontier.

Akira, Ghost in the shell, Patlabor, Elfen Lied, High School of the Dead are also quite enjoyable.
