Well, today mostly yes. But at the same time, I've been an Opera user (if not fanboy) for a good decade, until they ditched their own engine and basically started from scratch with chrome as a base. It lost 99% of its features overnight.
I really struggled to switch to anything else. Firefox was definitely the most customizable, but finding extensions to replicate every feature of Opera, and properly at that, was a never-ending nightmare.
Only at that point did I realize how vital a browser has become for everyday tasks, and as a power user, how much you get accustomed to it. Maybe not if you're just running stock Chrome or Firefox with two extensions, but Opera was so feature-rich that I didn't ever install a single extension but needed about a dozen on Firefox to try and mimic it. In the end I just stayed on Opera 12 until it wasn't even funny anymore. It must've been about two years. Eventually so many sites broke that I just switched to Firefox and only installed uBO and greasemonkey. It hurt but over time I just gradually forgot what using opera was like. Sometimes I think back and really miss it. Some of it is just nostalgia by now, but the struggle switching was real.
I don't remember when I tried it for the first time, but I did like it much better than the new opera. At least they were adding new features much faster. It was still different enough and lacking (to me) important features from the old opera. I still have it installed today as the fallback for the exceedingly rare case that some site doesn't work in Firefox and I really need to access it. But I have to admit that I didn't really bother to evaluate it properly in a long time. An ex colleague doing webdev just recently told me it's his primary browser as it has some nice things to make his life easier that were just more cumbersome to set up in chrome. I just gave up and accepted that at least by using Firefox I'm fighting the engine-monopoly of chrome/blink. ;)
