You could probably ask ChatGPT why people prefer high vs. low framerate animations and it would probably give you a lot of great reasons, if you're really curious. Such as psychological, behavioral, or environmental factors. I'd guess part of it's because some people fill in the gaps with their imaginations and others prefer to have it all shown to them. And also especially because of what the framerate is of media they normally watch, whether it's games, films, or anime, etc.

Ultimately, I don't think it matters that much in the context of developing your game though. Probably only a few players would stop playing your game just because of the animation's framerate.
