I have the earlier X100 and like it very much for street and casual use when I want to have something extra and light weight. I am even like its low light responsiveness. It is fine at 35mm equivalent fixed lens use---even have the wider angle adapter that takes it down closer to 28mm. The color and exposure is magnificent on this camera for DX equivalent sensor. In this forum, you will find some examples by others using the X100 camera.
I really, really love my x100s. I preordered and have had mine since it was released. I can't speak to the other cameras as I don't own them, but I'm familiar with their specs. For me, I appreciated the Fuji's viewfinder (especially the hybrid functionality), awesome manual controls, and SOC jpeg quality. I take it everywhere with me.
