Editor's Verdict
Editor's VerdictIf you care about actually using a browser with real features and day-to-day convenience, Opera is the only practical choice here. Chromium is just the raw codebase powering browsers like Chrome and Arc, and there's no reason for most people to use it directly, everything you'd want is already in those full browsers, not in Chromium itself.
Opera at least tries to stay current by copying features like Spaces (as Workspaces) and tab grouping, so you get modern conveniences right out of the box. Just know the Workspaces can't fully separate your environments since cookies and cache are shared, which is a real limitation if you need strict separation between, say, work and personal browsing.
But if you're just looking for something to use every day, Opera gives you a complete browser with features, while Chromium is only for people who want to tinker with the foundation and don't care about actual usability. For anyone who just wants to browse, Opera is the only real option here.
