Difference between Alpha 6000 and NEX-6

I'll be looking to purchase my first proper camera in the coming months. I've only ever used point and shoots in my life. I'm planning on going mirrorless since they're just easier to manage. Sony is naturally the preferred option when it comes to that.

Under the ~$900 range the two decent options I saw are Alpha 6000 and NEX-6. There is also an Alpha 5000 and NEX-5. I'm just unable to figure out any real difference between these models.
