[GERGE]

Only some of them are good enough to compete and only a handful of them can really compete at the same level. Alegreya, PT Serif, Ubuntu Mono, Source Sans Pro... Stil, there is nothing like Freight family, Arno, Storm Baskerville, GT Sectra... I can count many.

They might look as good as the others on the surface, but there are many details that would be missing. Good kerning, good hinting, ligatures, optical sizes... For example Open Baskerville was long considered one of the best free typefaces out there, just compare it with Storm Baskerville.
