Skeleton Screen or Loading Animation

I'm designing a loading screen for a website application. I'm having two options for this:

  • Skeleton Screen
  • Loading Animation

I haven't known how to choose one of them yet due to some reasons:

  1. I can't find any article that argue about using Skeleton Screen.
  2. There're many things need to consider when designing loading animation: UI Copy, Animation, Brand Identity.

Therefore, I can't decide which one is better than other yet. Hope to learn something today :D Thank you guys!
