I tried Opera a few months ago and could not stick to it. All the features they were pitching at me felt a little off. The various panel integrations were clunky and didn't seem to offer anything over just... tabs.

Maybe not surprisingly, I'm currently on Vivaldi (although it has its own issues of not infrequent slowness or hangs).

Don’t let Opera cloud your judgement since it’s a poor choice to start with.
