SigmaOS is a more unique productivity browser in the space.

SigmaOS tried to re-think how a browser layout should be, and build in layers of productivity along the way (not too dissimilar to that of Arc Browser).

The thing is, Sigma has quite minimal funding, and in the browser space, you're competing with companies that have billions of dollars to throw at improving the browser (Google Chrome, Edge, Safari), so when comparing it to those, it's tough to see how they'll manage to compete.

That said, even just comparing SigmaOS to that of Arc, Arc has raised over $100M to take on this incredibly competitive space, whereas SigmaOS is trying to fight having raised likely less than $2M. It's also tough to understand if people are actually willing to pay for a browser, and at $20/mo on the paid tiers for SigmaOS, it just feels like Arc is the more likely winner here.

SigmaOS does make some pretty different opinionated design decisions though, it's worth a shot checking out if you want to try something fresh and new, though not sure we'd bet on it ultimately taking up any meaningful browser marketshare.

Edge is Microsoft's attempt to stay relevant after all the years of pain and heartache that came from Internet Explorer.

Their large investment into OpenAI has enabled them to pull in some AI into the browser (branded as Copilot), though it's more just a wrapper for ChatGPT with various pre-built functions.

While Edge is built on Chromium (like many of the best browsers on the makes), they are one of the only browsers (aside from Arc) that have managed to exist without taking that sweet sweet money from Google.

Edge makes money by promoting their many Microsoft products, making them work more seamlessly in the browser where possible.

While Microsoft has tried so hard to get back the marketshare they once had and have since lost, Edge still feels a bit dated in their UI/UX, and their unique functionality isn't all that great unless you're an avid Microsoft 365 user.

That said, if you're on this site and doing software research, you're more likely using Google Workspace and Gmail, and there are much better browser options on the market, even if you're a Windows user, as even Arc is now on Windows.
