What's more expensive? iTween animations or baked FBX animations?

Hi,

I'm using Playmaker and iTween actions inside of it, and since I'm aiming at mobile platforms, I was wondering which way would be less expensive performance-wise: having a few Itween simple animations (move, rotate) or playing baked animations stored in FBX?

Let's say I have lots of simple static Enemy objects which I want to quickly kick out from the scene on collision with player. Of course I could animate those enemy objects making simple animation in Max, export it in FBX and then play it on collision with player, or I could basically achieve the same result having a few iTween actions (Move Add, Rotate by, Scale etc) in one PlayMaker FSM placed on that enemy object. But what would be your recommendation for mobile platforms?

These collisions with player will happen let's say once in 5 or 10 second period. Thanks in advance!
