So… why would I use any of them? All (?) OSes animate then anyway, and in a much less obnoxious way.

Do you want to :

( ) send flowers

For neither use case I'd use gaudy animations.

That's a question you should answer yourself, seriously :) Depends on your project and what you trying to achieve.
