Maybe times have changed LAX - but from many years on this forum I'll say that it seemed that AMF on the cargo side and Cape Air on the pax side certainly did hold some sway with recruiters when you are climbing the ladder. Good job/recruiters know of the type of flying involved in those positions and possibly give it more credit that extra CFI time (meaning there is a point when you've got your CFI experience and now they would like to see you continually moving up the ranks to different and even more challenging types of flying).
Unless you have sit across from an Atlas recruiter and s/he told you face to face that AMF flying is not looked upon favorably - - then I'll take your view as an opinion - and I thank you for that since I asked a question and you answered.
But weighted no differently than someone else' opinion that is worth a second look at a certain stage of a career.
