Interesting topic. Well I am trying for as much as possible to be objective here, so you'll have my guarantee on the utmost quality of story, characters, powers/fight scenes, graphics, soundtrack, production, classic scenes, dialogue and so forth, and all of them trying to fit in and combine as much as possible into one at once. After all, I joined just now specifically to answer in this topic.
I can't decide on a particular order, except #1 which probably has to have the best overall quality on all those things combined, that I EVER saw (and I saw plenty).
1. Cowboy Bebob: Stairway to Heaven (movie)
2. One Piece
3. Yu Yu Hakusho
4. Hunter x Hunter (original series, the OVAs were pretty bad)
5. Hellsing Ultimate OVA
6. Tengen-Toppa Gurren Laggan
7. FLCL
8. Dragonball (original series foremost, but you can count the others too if you want)
9. Neon Genesis Evangelion (series, End of Evangelion, Rebuild of Evangelion)
10. Code Geass (would have put this higher if I remembered what I wanted to say quicker)
And there you have it, full on win on everything. Granted, there are plenty of great movies that deserve mention, tho' I am a bit behind on watching actual anime movies, however I believe animes should take priority, because making a consistently good anime is harder than a movie, and good anime movies are often stand alone masterpieces.
Then again, I suppose plenty of the ones on that list aren't technically different since you left the anime scenes, but classic is as classic does. I never watch dubs so I can't vouch for them like that.
Also, if anyone dares to mention Naruto or Bleach, I will personally go over to where they live and gut them.
