@seancwopera Personally I've found that no one browser is better than all others in every respect. It's one reason I have several installed.
With respect to what i choose as default it's a matter of weighing up the pluses and minuses. It was very hard to shift me from Firefox as default. But eventually the shift from Classic to Quantum had just enough annoyances to make me call it a day.
I'd had Opera installed as an alternative from even before Firefox but, for various reasons, it never made default. But I'd always kept an eye on it. When it moved to Chromium I then, after a while, noticed that its usability was superior to Chrome's from my point of view, so I started using it as a better Chrome for use cases where I needed Chrome-like behaviour. E.g., as a freelance software developer at most sites the developers are using Chrome and typically debugging through Chrome. So I would substitute Opera instead to get a similar experience. Or sometimes I would use Chrome for debugging but switch to Firefox for regular browsing.
Meanwhile at home, after a certain amount of tweaking and extension discovery, I was able to decide that the Opera experience was now better overall than my Firefox one.
I still have Firefox installed and do keep an eye on what they're up to but I'm probably unlikely to return now - especially as I now have a political beef with Mozilla. Though my switch was independent of that.
