Was never much of an opera user, but I have enjoyed vivaldi quite a bit. I don’t see myself using vivaldi due to the chromium aspect. I used to keep it around for the random chrome-only sites but that’s way too uncommom nowadays.

Lately safari/gnome web (i.e. WebKit engine) have gotten good enough to be my pwa installer browser depending on my OS, though i really hope firefox re-implements PWA support sooner than later.
