I'm not that commenter but ctrl is my least favourite regularly used key to hit. It's not comfortable to reach with either my pinky or thumb. Command is basically where my thumb rests naturally, it's in prime position.
Yep, cmd is great where it is. If I compare cmd-shortcuts with identical ctrl-shortcuts, with normal key mapping, the ctrl ones strain my hand and pull my fingers away from the home row. The same cmd-based shortcuts do neither of those things. It's one thing Apple got very right, that everyone else is getting wrong.
