I have a Brothers Innovis QC1000 I just bought in April. It has needle threader, automatic tie off to start and a button to press to do automatic tie off and thread cutter at the end. Pressure foot can be by hand by push button or knee lift. Has other automatic features I am not familiar with yet. Also has a walking foot attachment.
I loved my Pfaff with the walking foot, however it was going in the shop about once a week, and I discovered Pfaff is now longer owned by Pfaff and is made in indo china or whoever gets the lowest bid. They change every 5 years and as mine was 5 years old, the parts are hard to find. It is really sad that such a great machine is going down hill. My daughter still has my old phaff which is about 15 years old. Just hope it holds up!
