The system Mercedes is using is extremely limited and hardly compareable to FSD in any way.
Drivers can activate Mercedes’s technology, called Drive Pilot, when certain conditions are met, including in heavy traffic jams, during the daytime, on spec ific California and Nevada freeways, and when the car is traveling less than 40 mph. Drivers can focus on other activities until the vehicle alerts them to resume control. The technology does not work on roads that haven’t been pre-approved by Mercedes, including on freeways in other states.

I would much rather use FSD that is limited to routes and conditions where the developers and testers agree that it’s safe.
Compared to a company that says “everything works”, and “those drivers that got killed must have been doing something wrong”.
