I own all three and my go to is the 201. I use it for piecing. The 401 is awesome, mine comes in the most amazing cabinet too, but I do not like it for piecing. It is a work horse and I would really consider it as I do not see them that often for resale. It is my DD's go to as she does jean purses etc. I would skip on the 15-91 as it is easy to get one used and I did not think it as great for free motion as my Janome 6500 or Bernina 830 , vintage. For me the machines do not work in different cabinets. For one the 201 has a longer bed.
