I can't answer, I love them both too much :P

I was never into Beauty and the Beast, but I LOVED An American Tail: Fievel Goes West!

I don't know about the other one so...

Fievel goes west is more nostalgic, but upon rewatching, it's not as great as I remember.

I've only seen this movie once (we watched it in class once in middle school, interestingly enough) and I liked it! But I've seen BatB more and I know I like it quite a bit, so I'm voting for it.

I've never seen the American Tail one, but I'm very surprised Beauty and the Beast is leading this poll on the DP spot against a lesser known film (perhaps a few people haven't noticed that it is asking for least favourite?)

Anyway, I had no idea they were released on the same day!

Because...I don't like Disney's version of Beauty and the Beast, preferring other versions that keep Beauty's siblings ( her sisters and brothers) in the tale as well.

But I didn't know that American Tail was released on the same day as Disney's version... So that part was interesting. It was 1991, and I was way young.
