Comparison Summary

Comet Browser lets you actually have its assistant handle your tabs, emails, calendar, and even browse the web for you, which Opera does not do.

Only use Opera if you just want a familiar browser with new animations, since Comet Browser gives you free agent features for research and shopping.

Editor's Verdict

Copy Link

If you want a browser that actually brings something new to the table, Comet Browser is way ahead. Its agentic browsing lets you tell the built-in assistant to click around, fill in forms, or even hunt for promo codes while shopping, and it's the only one offering that kind of hands-on AI help for free right now. This is especially useful if you do a lot of research or online shopping and want the AI to do the heavy lifting, not just answer questions.

Opera, on the other hand, mostly just copies features from newer browsers and dresses them up with slick animations. Their Workspaces look cool but don't fully separate your environments, which is a big miss if you need clean lines between work and personal stuff. No mention of any agentic or assistant-driven features, so it's just a traditional browser with some visual tweaks.

If you care about having an assistant that actively helps you research, shop, or manage tabs by actually interacting with the web for you, Comet Browser is the clear pick. Opera doesn't come close on this front.

Comet Browser Editor's Verdict

User Experience

You get a glimpse of what an AI-native, purpose-driven browser can feel like with Comet, especially if you're the kind of power user who wants an assistant that clicks around the web for you and pulls in email or calendar context. The interface is built to showcase these agentic features in a way that feels more user-friendly than most early AI browsers.

But the experience is rough around the edges. You run into moments where the assistant can't actually take action on the page you're on, even though the demos suggest it should. The workflow sometimes breaks down when you expect the assistant to handle something and it just can't, so you're still jumping in to finish the job yourself.

If you're an early adopter who likes trying new things and doesn't mind dealing with unfinished features, you'll appreciate what's here. For anyone expecting a polished, efficient user experience that just works, you're going to feel the inconsistency and friction.

Opera Editor's Verdict

What is Opera?

Opera has managed to stay about as relevant in the browser space as Firefox, which is just a tad bit behind that of Microsoft Edge.

Interestingly enough, unlike most other major browsers on the market, Opera is actually a publicly traded company with about a $1B market cap. This is particularly interesting because it means that they need to focus on growing revenue as they have investors.

Key Features

In their attempt to stay relevant, they have copied many features from the more modern browsers on the market like Arc Browser (e.g. Spaces and Folders).

Workspaces

You can tell Arc has been influencing the browser market. They expanded the idea of browser profiles into Spaces, and now Opera has copied the concept with Workspaces. The switching animation is slick and you can create as many workspaces as you'd like, but they all share the same cookies and cache, so you cannot fully separate environments like personal and work accounts. That separation is the key difference between Arc's Spaces and Opera's Workspaces.

Tab Groups

You can create groups of tabs in the top if you want similar sites to be together for easy expanding/collapsing. If you open up 2 or more of the sam site, it'll automatically create a tab group for that site.

Privacy & Security Concerns

Opera has been called out a bit lately for being owned by a Chinese company, and for making most of its revenue from Ads, meaning they very well are tracking, storing, and selling details about how you're using the browser.

Final Verdict

While tempting and seemingly impressive, there's just something in the heavy influencer marketing push and security concerns that make us have a bit of pause in actually using Opera as our daily driver.
