Best Anime from the 90s?

Some people in here were recently talking about great anime that's older. I mentioned I was watching Trigun, but it made me think what the BEST anime from the 90s are. I also love Cowboy Bebop and Outlaw Star....what are your opinions though?

Ahhhh It's really difficult to pick only one D:

I'm in the same boat as you, Taylor. I absolutely loved Cowboy Bebop. Slayers also ranks high, but if I think about the impact that certain animes might have caused in that period, I would say that Nenon Genesis Evangelion is the #1. It's so intrincate that nowadays I still can't get most of the hidden meanings.

DBZ in my opinion 

dbz is a 90s anime right 

Dragon Ball started in the 80s :)  DBZ is still in that time range (1989). I can't believe that this anime is as old as me hahaha.

Ghost in the Shell has got to be somewhere at the top of this list

Sailor moon, Revolutionary girl utena, Yugioh, Digimon adventure, Dragonball z, Cowboy bebop, Neon genesis evangelion all of those are my favorites ^.^
