I can't compare it to other manufacturers latest TACC (my old car had just standard cruise). However the biggest bonus I think with Tesla is that it can actually brake the car down to a full stop and restart it (which I have had the opportunity to test and enjoy 2x so far on interstate traffic). Worked like a charm. That coupled with autopilot made the stop and go traffic very bearable. I think other manufacturers have a cutoff mph that it can engage/brake down to.
