Is ⌥⌘⎋ Force Quit the same as Force Quit for an icon in the Dock?

There is a difference in 'Quit' and 'Force Quit'

Quit: This is the same as choosing File > Quit within an app. The process quits when it’s safe to do so. If quitting the process could cause data loss or interfere with another app, the process doesn’t quit. Also, if you are not the Administrator it will ask you for the Admin password.

Force Quit: The process quits immediately. If the process has files open, you may lose data. If the process is used by other apps or processes, those apps or processes could experience problems.

If what you are quitting says 'Force Quit', it means it as described above.

They are both the same.

When an app isn't responsive, the dock says Force Quit. That's what I'm talking about: That versus the Force Quit window.

Force Quit is Force Quit. It doesn't matter if you use keyboard shortcuts to do it,  --> Force Quit to do it, or right-click on the icon in the Dock to do it. They're all different ways to accomplish the same end.
