If I went back to the vi interface for some reason I’d at least use ctrl-[. I dislike lifting my hand more than I dislike using modifiers.

I used vi for a few years so have the muscle memory and the sole advantage in my perception was that everything is simple typing with hands remaining in the home keys position (except Escape, ironically).

So it’s more relaxed if you find using modifiers onerous, but I don’t find Ctrl or Alt significantly worse than Shift, and I don’t find it any worthwhile advantage.
