On Macs and iOS, and iPadOS, it's clunkier than Safari, but less clunky than Firefox.
Perhaps the Windows experience is similar.
I'm not normally a fan of Apple at all, and I have no interest in using Safari myself, but here I am glad that they've so far refused to jump on the Chrome bandwagon: it's good for keeping the web standards-based so we don't have a repeat of the IE6 days.
