Here's an  interesting comparison test of Tesla Autopilot and the Cadillac Super Cruise assistance systems performed by Edmunds.

As more and more manufacturers start to offer assistance systems, soon we'll see more comparison similar to this one.

Autopilot in the Tesla Model 3 (or Model S, Model X) is not the same as the new Cadillac Super Cruise in the CT6 model.

In the case of Autopilot, it can be engaged on a broad spectrum of roads and offers things like lane change. However, the freedom makes the system sometimes not capable of handling a certain situation (see how the Model 3 struggles on the wide lane). Anyways, Tesla cars are promised to be hardware ready for full autonomous driving and should continue to improve with new over-the-air updates.

As for Cadillac Super Cruise, the system is very conservative and limited to only major highways, without intersections or even roadwork. Unlike Tesla, Cadillac uses eyes tracking (even with sunglasses) instead of asking you to keep your hands on the steering wheel. In effect, all you need to do is watch straight ahead and enjoy hands-free driving, which is apparently more relaxing, according to Edmunds. The steering wheel on the CT6 with Super Cruise is special too, with an LED indicator that shows system status.

"Tesla's Autopilot and Cadillac's Super Cruise are the most capable driver assistance systems available and provide a glimpse toward the future of self-driving cars. These semi-autonomous driving modes aren't the same, though. And while Tesla's Autopilot has been deployed on the Model S, Model X and Model 3, Super Cruise debuted this year and is available only on the Cadillac CT6. We drove an Autopilot-equipped Tesla Model 3 and a Super Cruise-equipped Cadillac CT6 to explore the system's similarities and differences in the real world."
