Another thing you might not realize is that Mac spacebars are narrower, which puts the command keys closer to the center of the keyboard where they can more easily be reached using thumbs. Alt on a PC keyboard is harder to reach than Command on a Mac keyboard.

Not to mention getting pinky syndromes from using ctrl so much.

It feels that command being close to thumb (macOS) is a much better design than using pinky with control (Windows)

I often press Ctrl with my thumb though.

I always use my thumbs to press command in shortcuts, and I never had a problem with the location of the command key
