I hate animations on most devices. On Samsung's I always either turn off or go to 0.5x in developer settings.
On iOS I turn on reduce motion in settings. This makes the whole thing fly without silly zooming animations. This gives it same quickness as best of Android.
Sense 6 is surprisingly fast though with default animations and lollipop on my Moto X isn't too bad, but yeah Samsung and Apple by default are horrible.
Windows Phones needs the option to speed up or turn off its animations too, it is one of the slowest UI's (though always fluid) because of its animations.
I usually am not a fan of animations and reduce the speed, but for some reason they do not bother me on IOS. Actually turning them off on IOS bothers me b.c there is still a delay before you can interact with the app or home screen.
