It may look like it works "just as well" but that's not true. There are numerous things that impact performance and effectiveness that are not possible with chromium-based browsers, or at least have to be done inefficiently, including
* pre-fetching
* html filtering
* use of WebAssembly
* data compression and private/incognito mode
Edge has its own extension API in addition to the Chromium one, it's possible that they've managed to mitigate or eliminate these problems.
