I don't personally remove snaps but if I did I'd still use Ubuntu for the sole reason that it is somehow the only distro that gets fonts right. I don't know what it is but on every other linux distribution font rendering looks horrible, and I could never figure out how to reliably fix it.
It’s most likely not the rendering but the font itself. The Ubuntu font might be the best looking one around. It can be installed on other distros easily. Some have it packaged in their repositories. Switch fonts, turn on full hinting and you’re in business.
I don't think it's just one font. I recently switched away from Ubuntu to OpenSUSE TumbleWeed and on occasional webpages and applications I get these badly rendered fonts. I fixed them to some extent by installing additional fonts, but not completely.
I know what you’re talking about. IIRC, there’s a page in the OpenSUSE docs or in the forums covering the bad browser fonts. That’s an issue that’s specific to them. Haven’t seen it in another distro in many years.
