Unless your career goal is to work at AA or United in 3 years after getting paid $30k per year less than your peers at other carriers, I’d avoid 9E. Delta has made it clear that they’re only interested in hiring you after you’ve “paid your dues” at their gOLd StANdaRD ReGIonAL. They will not hire you if you try to “jump the queue” and leave 9E in a “lateral” move to B6, F9, NK, etc.
