I would argue, that a more narrow font gives you more bang for the buck in terms of information per area of foveal vision. Even if something looks aesthetically more pleasing, if it serves is purpose better, you'll get used to everything else.

My history is: Monoid -> Iosevka SS05 -> Essential PragmataPro

I just compared the latter two to JetBrains Mono, and at least on my settings, doing a blink comparison, they both look more clear to me.
