Best for each decade, and ranked from best to worst, based on this list:
http://www.ultimatedisney.com/ultimateclassics.htm

90's : Lion King
40's : Fantasia
50's : Sleeping Beauty
80's : Little Mermaid
00's : Fantasia 2000
30's : Snow White (the only film, but still beats the 60's and 70's)
70's : Many Adventures of Winnie the Pooh
60's : 101 Dalmations

Bit to tough to judge the current decade. Not enough time to judge some of these films longevity.
