Personally, I prefer the glide 2 animation for windows. Fade feels like
a better fit for 'transitive' windows, like menus or dialogs. The glide
2 animation is a tweaked fade with slightly more impact - which
conceptually fits application windows (they have more impact than simple
menus).
The difference is subtle though and I don't feel strongly for it. I just
felt a strange vibe when I used the KDE compositor, which I eventually
linked to the fade-in animation: application windows behaved exactly
like menus!
