I posted this comment[1] in the previous discussion. Reposting here, because I don't like slightly-derivative typefaces that are just FontForge tweaks of a typeface that was designed from the ground up, even less if they have given it an entirely new name.

All glyphs are indistinguishable from Source Sans. The 'thin'/'light' weights are kerned further apart (and in my opinion, worse) than in Source Sans. Given these, why does this typeface deserve a new name? It is Source Sans, full stop.

At least Arial (Helvetica copy) and Segoe UI and Myriad (Frutiger copies) have a handful of distinguishing glyphs.

I have a very hot take—with typefaces, you absolutely get what you pay for. I don't like the vast majority of SIL Open Font Licence type faces, with a handful of exceptions. Most of them have glyphs that are an absolute eyesore, are weighted, sized, hinted, and kerned terribly, don't have any character whatsoever (they're all copies of copies of copies of Helvetica) and don't encode nearly enough glyphs/combining marks in Unicode.

Hint: if I can't type IAST/ISO 15919 without tofu showing up, then the font doesn't have enough Latin glyphs.

The majority of digital fonts are either not hinted at all (which makes them look like crap on low – medium resolution monitors), or appear to be hinted on and for macOS, which doesn't have sub-pixel anti-aliasing, but rather greyscale (i.e. full-pixel) AA. The result looks quite bad on Windows and Linux. It looks bad on macOS in monitors with lower pixel density, too.

I will gladly pay for a well-designed typeface (or by proxy, pay a font database subscription). The effort that designers have to put in to design something new from complete scratch is immense. Designers have to come up with unique glyphs, and then when actually setting up the curves, then have to think about how the typeface will vary along several dimensions: weight, size, display pixel density, print versus display, and so on. It's no wonder that the best fonts cost thousands.

Good fonts that have both character and are immediately legible without being unnecessarily fancy is an extremely fine line to tread and in my opinion only a handful of typefaces have managed to balance all of these through the centuries. Some of my favourites follow.

Sans-serifs include Helvetica, Frutiger, Futura, Myriad, Johnston, Optima, Transport, DIN (and its many variants; my favourite is FF DIN), Ocean Sans, and Segoe UI.

Serifs include Roman-cut (including Trajan), Garamond, Minion, a handful of Didone types, Berkeley Old Style, and Palatino.
