i've only seen a couple other series...
i liked Trigun alot.
as far as movies, i think Blood: the Last Vampire is worth renting (but not owning - beautiful animation, not alot of story). Jin Roh (sp?) i think is also worth renting - very surreal, in an Akira sort-of-way, but no sci-fi about it
otherwise, i've only seen the first couple episodes of Berserk and Evangelion, so i don't know much about those...
almost forgot-i have seen the first Lodoss War series, which was o.k., they get bonus points for being d&d anime (watch the battle scenes), but you can tell they ran out of money (like most series) when the animation quality drops
