Honestly, on the high-dpi MacBooks (my 2015 13" rMBP and the 16" MBP), I decided to run 100% rendering (which needs to be done with Retina Display Manager). Chrome on 150% default zoom, and VSCode on zoomed in + shortcut to +/- font size easily. Most other electron based apps (Spotify/Todoist) zooms pretty well too. Pixel alignment with round scaling means much better font rendering. UI elements are a bit too small though. But worth the tradeoff to me.
