There isn't a single good open-source browser.

Chromium relies on Google too much. Firefox will turn into an AI browser, and it's just too slow to use any of its forks (that involuntarily delay security patches). The company behind Brave has done shady things in the past to its users. In CLI browsers it's not really possible to show a picture, or easily play an audio file (at least in Lynx).

Major web browsers aren't made for users anymore. Minor browsers are lacking features and performance.
