As I said before: for what I shoot (wildlife, macro, landscape) no ML system can get a shot that I cannot.
as I've said before for what I shoot as a paid pro , sports (20 fps vs D6 14fps, while quiet , weddings , ballet and theater where churches won't allow a loud mirror flapping sound, events , large landscapes (Z lenses are sharper than their F mount versions) , taking pics in dim venues EVF much brighter than dim d6 ovf, EVF shows me what sensor is exposing in real time instead of having to take picture on D6 than have to review after in screen , video the mirrorless Z9 is superior to any DSLR I can keep going
