It depends on what your purpose is I suppose. To me, Firefox is nicer on Pc. I like Brave on smartphone too because, for now, I can just have free ads internet and I can't stand their intrusion, even though it's partly based on Google...
I'd said that duckduckgo long betrayed people and stuff like Ecosia aren't really a thing for the planet, but more a greenwashing initiative.
If you want the best browser compatibility then go for chrome, if you want more features then go for edge, if you value privacy firefox, tor and are good choices, most of the rest of the browser kernels you can see are basically chrome's kernel such as opera. but there have been reports of chrome peeking into the user's in untraceable mode browsing history.
