Reminds me of Ford Vs Chevy. All the major brands get you where you want to go. Nikon and Canon both yield excellent results. Most brands try to maintain some kind of backward compatibility with lenses because it helps sell the new generation of bodies.

Loyalists are almost never familiar with the other brands and not qualified to make fair comparisons.

I’m glad you are happy with Nikon. I’m happy with Canon. If I went with Nikon, my pictures would probably look the same and I’d still be happy.

I have shot Nikon since 1971. The oldest lens I own is a F mount 13.5cm 3.5 Nikkor c.1963. Which I purchased used as my first 135mm. My first 50mm 1.4 was also purchased used - made in 1969. They mount and operate on my Z9. Kinda clunky but works correctly. And on my Z7, Z6, D850, D200, and my F. Most of my AF, AF D and previous lenses will mount and operate manually on the F. Even the old F mount intrusive fisheyes will (mostly) mount and operate properly on the Z camera’s. I’m annoyed that my screw AF lenses don’t autofocus on the Z series with the FTZ. But otherwise they work fine.

During the same time period Canon has had the following lens mounts:

1959 R
1964 FL
1971 FD
1987 EF
2003 EF-S (EF compatible)
2012 EF-M
2018 RF (EF lenses can be adapted for the the R camera’s.).


Note for the ignorant:
R, FL and FD are the same mount.
EFs is so crop lenses are not wasted on FF cameras.
EFM will take EF lenses and work just fine.
RF will take every single EF lens with adapter and work 100% or even better especially with the control ring.

Nikon "Mount" changes using your logic:
Pre AI not all worked with AI and could not be converted.

AF-P
Z which does not support but a couple of all the previous lenses including auto focus lenses.

Z orphaned thousands of Nikon owners with un-useable lenses as shown in compatibility charts, and even in the older mounts there was a lot of incompatibility, thus the need for compatibility charts.

100% of EF/EFs lenses are fully compatible with the RF mount with the adapter. (EF lenses have been around for 35 years and anyone under 50 would likely have no clue about FD lenses and could care less) Additionally ALL FD/FL/R/M39 Canon lenses work on the RF mount cameras. So those that still have those great lenses now use them again with the latest R cameras.
See photos, ALL have the same identical mount and I have mounted ALL on R/FL/FD cameras interchangeably.
The last photo has FD/FL/R lenses mounted on all the cameras shown and NOT on FD/FD but so called mixed mounts and as you can see they all mount just fine.
Your ignorance shines through loud and clear.

I went with Nikon originally because the Canon FL to FD mount change seemingly left the FL user base abandoned. More specifically, the FD used market was non-existent.

That was then. To give Canon it’s due were I to have started serious photography in 1991 or later I might have gone with them. They’re offerings have always been impressive.

My 1st interchangeable lens SLR was a Canon FTb-QL. I had labored over the choice between it and a Nikon at the same price. There were 3 differences, in my mind: Canon had an all black body, Canon had 50mm 1.4 as kit (Nikon 1.8), … and the decision in my mind was Canon camera to lens connection was internal and Nikon had an external pin that mated to a tab with slot. “I thought” that Nikon approach made it more fragile.

Stayed with Canon and started our daughter with a Canon SLR film camera.
