Ok, first off, don't listen to any of them, none of them know what the fuck they're on about.
Throwing in choppy and easing into there, just doesn't help you.
It seems to me like none of the anims were really choppy at all, they all flowed, and had pretty much all of the frames needed for people to know what was going on, now next is the easing.
Nothing moves at the same speed as everything else, and things don't move at the same speed all the time.
Think of it like this when you drop a ball it leaves your hand with no speed. Gradually it increases speed, then it hits the floor, bounce back up, and due to gravity, it slows down, until it stops, then it falls back down.
Rather simple really, but probably the biggest skill needed in animating.
Hope this helps.
