Earlier quoted context omitted.
I like that in spite of this requiring two fingers, each finger on it's own has to move less distance than one would in order to reach Esc.
Remapping Caps Lock to Control makes the motion even easier.
I have a couple "HHKB" layout boards which do that. It is quite helpful!
What I have found even more useful is triggering a "layer" when Caps Lock is held down, which turns H, J, K, & I into an arrow cluster; U & O into Page Up / Down; and P & ; into Home / End. To toggle regular Caps Lock, I just activate the layer and then hit A. It's a big time saver! :)
