OMG, Jungle Book, far and above any of the others listed.
Great voices, characters, Great Songs, Beautifully
animated, Classic Story! none of the others blend
those things together as well as the Jungle Book.
And it's really the last Animated movie that Walt
oversaw development of. After The Jungle Book,
the original Golden Age fell. The animation dept
really struggled to get great stories like they used
to produce. Until the 2nd Golden age started
with The Little Mermaid.
2nd in line, I would choose Aristrocats. There is
some good music, but not near to the level that
the JB had. Story seemed a little bit of a re-tread
of 101 Dalmatians, But doesn't have nearly as
great of Villains.
