The deal-breaker with Hack, for me, is its curly quotes—they are just far too indistinct. A lot of monospace fonts make this mistake, although there's a pleasing number featured here that don't.
IBM plex mono also won out for me, although I’ve been using Fira Code for ages.
I used this to pick IBM Plex Mono for Gwern.net, which narrowly beat out the Adobe Source Code Pro which ranked highly & we had been using before.
