Fuji X20 or X-M1?

I'm looking to buy my first (non-iPhone) camera. I've decided on a Fuji (I love the retro aesthetic), and am trying to decide between an X20 and an X-M1. Surprisingly, they are priced approximately the same where I am (the X-M1 is a little more, but still within my price range).

They are clearly quite different cameras, the X20 being fixed lens. What would your advice be? Which would you choose?
