one is an older model but it is a " flag ship " model, one is not - it is a consumer level camera body
however, which does what you want to do best ? do you want one that allows you to " grow " ?
choose that one, not the one most recommended if the one most recommended doesn't fit your particular wants and needs
as far as using a camera and lens in " the dark " or low light, I look at the lens and how fast is it ?
F ?
but again, I claim no particular expertise, I just tend to post a lot
