is NEX 5/7 series equivalent Fuji X100 - both have APSC sensors

is NEX 5/7 series equivalent  X100 - both have APS-C sensors.

1) Like to analyse IQ, AF, contrast, Low light for these 2 cameras and they both APS-C sensors

2) Design/Body wise, I see X100 has an advantage as the depth of 50mm and has viewfinder (checked in Frys)

3) X100 dont seem to have any Auto modes, so is for advanced users
