> Why reinvent the wheel when you can just use this and it would use browser's default sans-serif font setting? I've done lots of testing and very often a font stack gives better looking results than simply using the default. People who came up with these font stacks didn't do a bad job at all. I'd say it's especially noticeable on Linux (but not only): the default may really be freaking ugly compared to one of the previous font in the stack. > Which users can define to whatever they want, system font or not. But most users really don't bother do that. Heck, out of simplicity I don't even do it: the reason being I like to see how others are using fonts on their sites and I don't want to always turn my font overrides/default on/off. I want to know if the sites looks good "without any user intervention". One problem with font stacks though is those who picked one then forget to update them when new, much better, fonts installed by default comes out. For example a shitload of websites on the latest OS X / M1 macs are going to fall on Helvetica first (because they use outdated font stacks) and use that even though the world as really moved on and came up with incredibly better looking screen fonts than Helvetica (I'm not saying Helvetica doesn't still have its place in print).
