It's just familiarity. I use Firefox on macOS and I always think the fonts look fuzzy on Chrome when I'm occasionally forced to use it. I spent a few weeks on Arc (Chrome-based) earlier this year, got used to the fonts, and then they looked a bit weird when I came back to Firefox.

I hate the Chrome fonts for this reason.

I'm surprised Mac users are noticing a difference though, I find the difference basically vanishes on really high res displays (like my QHD-ish panel on my Framework 13).

Pixels aren’t noticeable anymore in such resolutions but font rendering and anti aliasing may still impact perceived contrast and crispness.

Though, on such displays, disabling AA totally is a viable option but it will still feel different.
