I'm a big fan of Eliza. Klasky Csupo had some great female role models in their shows. They featured interesting, independent and rounded girl characters, which are a rarity, especially today. It's too bad they're no longer around.
Also this show pretty much rocked. I was a huge animal nerd when this was on the air, so I watched along with my little sister when it came on, and it was very accurate and never dumbed stuff down for its audience. Also, Tim Curry was the voice of Nigel! How awesome can you get?
