I use it on android as it’s privacy focused and allows encrypted sync across devices.

Works for me as I’m a phone and tablet only user with no desktop to organise sync.

I’ve tried others like Firefox but don’t like the interface on android tablet , no tabs so is just a bloated phone app. I tried opera but it doesn’t support my password manager so I’ve ended up sticking with Vivaldi and to be honest it’s a good overall experience.
