Tim Burton is alright, i honestly don't get why ppl love Nightmare before christmas so much cause aside from the characters design i don't see what's so special about that movie but i do love Pee wee's big adventure and Edward scissor hands.
Disney on the other made such amazing animated movies that it made japan go "HOLY SH*T" cause in a way, it was Disney that first legitimized animation as a respected source for good storytelling. They made movies that parents could enjoy AND could be proud to show to their kids despite the movies being racist and hiding subliminal messages in them.
That's all kind of badass imo, that's selling you magic in a bottle while giving you the middle finger.

i know this doesn't prove Disney films are better than Tim Burton's but i think it proves how historically significant they were.
