I think you would miss more than the automatic thread cutter!
However, they are fun to sew on, and it feels good to me to feel the link to the past when sewing.
Due to my height and bad vision, I cannot see the needle comfortably, because the tension knob is in my line of vision. Therefore, I have sold the FW's I have owned and now have 301's (slant needle). I use them a lot of the time.
