With my pinky on left control I can reach from A to K. With my thumb on command I can reach from A to J. With my pinky on command I can reach from A to L, though reaching A contorts my wrist in a way where doing that too much is gonna get me a real sore wrist real quick.

I've got to conclude that the reach between control and command are approximately the same, more than half the keyboard for me in any case at which point you should to switch using control or command on the right side of the keyboard, or using your other hand to press the second button.

Personally my biggest gripe with command over control is that a bunch of software still uses control on macos, giving a rather inconsistent user experience.
