As a kid, I found Disney cartoons unwatchable (and M-G-M cartoons not much better). Even some Terrytoons like Heckle & Jeckle were more entertaining (check out their Jimmy Durante-esque song and dance in "Taming the Cat").
The post-Leon Schlessinger Warner cartoons were more of a team effort by people with a great sense of humor... at least from the directors on down (not so much the producers and studio types who appear to have had humor deficiencies). Much of their continuing value is that they basically were written by and for adults.

The original run of Animaniacs was much the same.
