It really, really depends on what sort of websites you visit. I use FireFox as my main browser, but at least once a week I have trouble trying to do something on some website that only works on Chrome and its descendants. I'm sure you're not lying, but given you also say "most sites work with JS off too" I can absolutely tell you're not the average internet user. But yeah, we're discussing using eww here, so I'll accept none of us are.
