This is completely incorrect, and the solution is way more discoverable than needing to know obscure things like Win+E. Click the thumbnail that appears in the bottom right, then click the marker icon.
> For example, "open two file browsers, navigate to $home in one and $downloads in the other, move and rename a few files between them" is a 10 second task on Windows (Win+E x2, quick clicks on the explorer links, easy to scroll around, move files, drag, rename, anything you want).
Similarly, if you know the platform-specific shortcuts, this is less than 10 seconds on macOS. Click finder in dock, hit Command-N twice for new windows, drag each window to one of the L/R edges of the screen to tile, click downloads in the sidebar on one, click the home icon/username in the sidebar on the other.
I haven't used Windows since the early days of 10 when I moved wholesale to Apple, but let's be really real - Apple users mocking "obscure shortcuts" in other OSes is throwing stones in a glass house:
Cmd+` to scroll through windows of the current app?
Cmd+Option+H to hide other apps?
Cmd+Shift+Ctrl+4 to clipboard copy a screenshot?
Quick, is Mission Control a three finger swipe up? Or down? Or is that Expose?
Cmd+space,Cmd+B to search web from Spotlight
Cmd+tab, release tab, press Q - quit app without switching to it
Cmd+tab, then down - Expose.
