I'm probably getting downvoted for this but I switched from Google's Chrome to Microsoft's and i've seen a significant increase in performance especially with a lot of open tabs. Microsoft definitely removed something or optimized. And indeed they have anti-tracking features which google doesn't and ublock origin works unhindered.
I agree, I switched to "Edgium" at work months ago, then more recently at home, and I noticed a clear improvement in performance compared to Chrome. It even stayed past the "fresh profile" grace period, so it's not just a matter of no cache/info/etc. This is with the same few extensions, same use cases, etc.
