Yes it is.
Old system. Move hand to mouse, zoom out/scroll, assess bodies, move hand back to joystick, jump.
News system.
Open FSS, see what's there, close FSS, jump.
Basically unless you can actually post times for doing both then all you are doing is expressing an opinion. Mine is based on experience of the two systems and how I explore.
Just a note.
Zoom out is not required on larger monitors. Except on some very extreme cases.
Most HOTAS have POV controller and this + other HOTAS controls can be configured to operate the system map just fine. No mouse is needed.
