Fuji X-E1, Olympus E-PL5, or Sony NEX6?

I was sort of on the fence about the NEX cameras or MFT about 2 years ago. I ended up choosing MFT primarily because of the lens selection, but also because of the great deal I was able to get on an Olympus E-PL1. You're probably not considering an E-PL1 now, but I think lens selection is still a big factor in your decision. If I had to pick my favourite body, I'd probably go with the...Sony Nex6. I really like Sony's camera body's. They seem like great quality and the latest tech. Again biggest issue was lens selection which was just poor at the time.

I don't know too much about Fuji but I'm sure the IQ is fantastic and everything is great. If you don't mind the slow auto focus and heavier/bigger equipment, price, then it's a great option out there. All depends on what your priorities, expectation, and budget are.
