I'm not sure we have the same definition of "techniques".... Features are what comes on your machine. Techniques are what your hands do with those features.
I have several vintage machines, and a Juki 2010Q and also a Juki long arm. I am happy to sew on my old Singers that only straight stitch, but do love the features on the Jukis... the auto thread cutters, the needle up or down features, and the awesome throat space.
