Better experience than flying an RJ on AP? Yes. But it has little relevance when you eventually want to fly an RJ, 737, A320, 747 or whatever you eventually want to fly, on AP. If your end goal is for sure 121, and you cannot see yourself doing anything else, then AMF and the experience it gives really doesn't help... I loved the experience I received at AMF, and I am still not sure if I want to go 121 or not so thats the route I took.
