Should I trade Iphone 4s for Motorola Atrix 4g?

I have a Motorola Atrix 4g (my old phone) and I'm thinking about swapping it with my iphone 4s.
Is this smart?
Also, will the Motorola Atrix 4g have kitkat 4.4?

Depends if you like iOS or android. I've had both and I prefer the simplicity of iOS

No! I had this phone and it is garbage! Don't do it! Keep the iPhone and no it does not support Kit Kat.
