Eh, I don’t really think any are particularly unusual. Although I have tried some over the years.

I use Firefox on all my PCs which are all various distros of Linux, as well as Chromium for some things. I have a few sites setup as their own webapps using Electron, so essentially also chromium. I just installed Vivaldi recently to try for some things I need to test, haven’t started using it yet. I also try out different ones now and then.

Safari on my iOS devices as well as Aloha, OperaGX, occasionally Firefox but their iOS implementation is really sad. Some others now and then, but that’s mainly it at the moment. There were some I stopped using for one reason or another. Long ago I used Brave for a little while until I read about their agreements with some ad companies so that’s out. I really like Phoenix browser except it’s got some issues. Osiris, Puma, Dolphin, ugh so many that come and go if I need something temporarily.
