First is the correct gear for
Parking as it has the most engine compression to hold. Parking brake should generally be used and aleays on an incline. A manual relies on the clutch disk/flywheel resistance and engine compression to not roll. An auto has a parking pawl that engages.

The only time I don’t use the parking brake is when very flat directly after washing, snow, etc to prevent pad stick. Otherwise always whether auto or manual. In autos you take pressure off the parking pawl and save wear and tear on that mechanism of the transmission if you use your parking brake correctly (engage brake before engaging park).

So many folks today, not this crowd, don’t learn correctly because their driving trachers may not have ever driven a manual.
