Same as last time. Beast becoming a mediocre looking guy is far below Cinderella's magical dress transformation for me... a dress trasnformation which is Classic Walt.

Both are amazing. But here are basically the end results:
Cinderella's alright rags turn into a gorgeous ball gown.
Beast starts from a somewhat good-looking beast and turns into a guy that looks only alright in my opinion.
Besides, Cinderella's transformation is iconic and known as Walt Disney's favorite piece of animation.

I just love more the beast tranformation.

By far. Cinderella's so iconic and timeless.

Both are good, but the beast's transformation is undoubtedly the best, in my opinion. The animation is so skillful and is accompanied with the perfect music.

Cinderella´s dress might be iconic but Beast´s changing is more intense.

This is so tough! Both of them are amazing in their own way. But just as ApplesauceDoctr said, Beast's transformation has better animation and music. I also like intense scenes that can send shivers down my spine, as CodyVenusTrent said. So Beast changing back to a human wins for me.

Both are outstanding, but the transformation of the Beast is more challenging for an animator. I mean, they do a close up on his face while it changes.

No contest here, Cinderella's scene is simply epic <3

This is just too simple. I understand it's iconic, don't get me wrong. Cinderella's dress is covered in sparkles and poof!
Beast transforming back has more details! You can see his hands, feet and face change!
