Personally my favorite tv shows on the Disney channel are the ones that are not animated. I like The Suite Life of Zack and Cody, and The Suite Life on Deck. That's So Raven can be funny, but can also be really annoying. Phineas and Ferb isn't awful, but it's not my favorite.
I personally love hannah montana. My 10 year old stayed up all weekend watching her reruns she is in love with her and I think she is a ok role model for my young daughter. I also like Thats so Raven. She has been with me my whole childhood so I am glad she is in my childs.
In my opinion most all of them are really good shows. Off the bat I would say that Wizards of Waverly place and Suite Life On Deck are my favorite so I would say they are the best. They also have the older shows still on like That's so Raven, and newer like Good Luck Charlie which are good, also.
Disneys best shows include the following: Ducktales,Life with Derek, Lindsay McGuire, Hannah Montanna, The Oz Kids, Bump in the Night, Ready or not, Dinosaurs, Sabrina the animated series, and the Little Mermaid.
