The new Edge is here, promising more extensions and a far better search engine, based on Chromium, the same engine powering Google's Chrome browser. This makes it more compatible with websites other, less popular browsers have problems with.
This also means that after granting Edge permission, it can use Chrome extensions from the Google Playstore, which has far more than Microsoft's.
Downloading and installing are explained in the linked article, above. You don't have to uninstall the old Edge which is based on MS's engine.
Over the next weeks and months, MS will be pushing the new Edge. You can wait, and it might even be better to do so as just now it probably still has bugs, but if you like being on the bleeding edge, so to speak, go for it!
