@ben So many for either side, but let’s pick a few:

Favorites:

• serif: Plantin, Bembo/Aldine 401, Melior, Fern, IBM Plex Serif
• sans: Optima, Univers, Antique Olive, Fira
• mono: Courier Prime, EGA, Pragmasevka, Monaco (this category is more volatile than others)

Not so good:

• Souvenir, Spectral, Brush Script, Bookman’s swashes, Monos with script-like italics
