CORRECTION:
GCR was used on Apple2, 400K/800K Mac, Commodore, Sirius/Vector, etc.
That should read Victor 9000, NOT Vector [Graphics]
Vector Graphics was hard sectored, and not GCR.
Northstar is probably the best known of the hard sector formats.

Vector uses gcr. Apparently.
I’m not well versed in any of this, just relaying stuff i read from the
Applesauce discord support channel. People ask questions like all of yours
there all the time.
Join it and scroll back on that channel. Lotsa interesting stuff.

I know you do this for a living and are good at it. Most of us don’t do it as a
living but have piles of floppies that we want to recover cheaply using an
existing method. Grease, cat and other wezels, are fine but you have to do
more work to get usable stuff, unless your floppies are all c64
