Been discussed 1000 times... I don't care. Amps sound and feel better to me and I am no longer gigging so that is irrelevant to me. I'm playing at home and jamming with friends. I would NEVER use a modeler for that and I have seriously tried to make it work for me. I have owned several FRFR monitors including the Forum favorites (Xitone, CLR, FBT, RCF, Matrix, Fractal into power amp return of tube amp, etc). They all sounded strident and artificial to me. A FRFR monitor will never sound and respond like playing through a combo amp with an open back cabinet, which is my preference.
I do use the FM9 weekly at Church with in ear monitors because it is by far the best solution for that setting. And I love it for recording. I also occasionally use the FM9 for effects with my amp but I'm really more of a straight into the amp kind of guy. But if I were still gigging, I would use the amp.
YMMV.
