Brave is not your alternative because it doesn't have not a sidebar and you cannot split the screen on using the sidebar.

Whale is the best alternative for those wanting to use Sidebar, it has in and out of browser(widget) Sidebar that can be docked either side of your screen. And almost every feature(dual tab, vertical tabs, sidebar, floating always on top mobile view)

Also when you use adblocker, it also works on sidebar unlike Edge's sidebar.

I abandoned Edge like 6 months ago for the same reason guys, they are killing the browser, admit it.
