Another happy pfaff owner here. I love the stitch quality, the auto-pivot , the idt, the free motion foot and the lighting. The performance 5.0 is my newest machine.
We all seem to find machines that we love but I really think you need to try different ones to see what one seems best for you. Maybe there isn't a BEST machine for everyone but there are features that will frustrate you to no end and ones that will make your sewing time a pleasure.
