Of course there isn't much difference because Chromium is basically Chrome. There is no single independent Chrome/Chromium fork today meaning that they are the same. Everything Google adds to Chrome get down to Chromium. Sure you can (maybe) cut some telemetry but functional changes stay. If Google decides to switch some protocol handling, or deprecate stuff, or add stuff it all propagates to all mods of Chrome.
Edge is dead and closed. Chrome-Edge will indeed gain market share and it is better than nothing, but I dispute that it is an independent browser making independent decisions about browser engine and other important stuff (not about GUI and telemetry).
That's what I meant. Though I guess they've decided to take the google route in deploying manifest v3.
So I'll probably be dumping them for firefox (or rather, reversing how I use them. Use firefox for my 'logged in' browser and edge as my 'noscript, no cookies, no history, default browser')
