I think putting ctrl on the capslock key is the more efficient move, honestly. But Vi was designed for a machine that had esc where your tab is. It's built for efficiency but you lose all of it when you have to physically pull your whole hand up off of the home row. The Vim wiki has a lot of tips for more efficient mappings[1], but if you don't want to be dependent on your own idiosyncratic config, ctrl-[ is literally the keycode that the physical esc key generates, and it's soooo much easier to hit there's no reason not to retrain your muscle memory to prefer it.
