I'm migrating fron Firefox to LibreWolf (sorry, I prefer non-chrome based browsers), but have a Ungoogled Chromium as a backup those times Firefox/LibreWolf doesn't cut it (I thought the world had learnt a lesson from the IE days; seems we need to educate a new generation web hipsters).
On Android I use the default browser (in @e_mydata@mastodon.social) for a few news/blog sites, Mull and Vivaldi for some other sites and DuckDuckGo when searching. Default browser is Mull with Privacy Mode enabled by default.
I honestly don't like that the Chrome based browsers seems to be dominating these days. We need a heterogeneous web render environment to ensure a single dominant player dictates how things will be for users.
And without such competition, I fear there will be a lesser drive to further improve browsers. Just like when Netscape seemed too complacent with their own browsers back in the days.
