My answer is yes different machines excell for different tasks. My Pfaff that has the IDT (built in walking foot) is so wonderful for regular sewing, piecing quilts and stitch in the ditch quilting. However my Viking D-1 is an embroidery machine but has wonderful built in stitches that are great for quilting and deco sewing that the Pfaff doesn't do. Also the D-1 has a walking foot but requires you to put in a different shank to install so takes a little time to adapt. I love both of them.
I have never traded a machine in and have kept them all including the old Bernina in the red case that I let the grand kids sew on. Plus three old singers.
