I don't have a FW, but I do have a 301. I love it, and sew on it more than the 15-91, the treadle, the Wards signature, the old Kenmore, the Viking Rose, or the Pfaff expressions 3.0. But I do still sew on the others. I just do different things on them.
I primarily use the 301 because I can sew in the evening or at night, and not keep anyone up (except the cat, he thinks he helps me sew). The 301 is such a quiet machine for an electric. It just barely makes any noise, or at least mine doesn't. So, I think you'd like it. It is just a bit bigger than that of your FW.
