From a cursory glance, I can see that scoop is installed in your $env:LOCALAPPDATA path. While Chocolatey is, by suggested default, installed in C:\chocolatey\. This is a plus for scoop since installing in your root is usually bad practice and can make managing your machine more difficult for systems administrators. This also allows a standard user to install applications without administrator approval. (so long as they can execute unsigned PowerShell scripts)
Exactly something that could have been pushed into Chocolatey. The biggest thing about these kind of tools is to add and maintain the packages. Chocolatey has been gaining momentum and has a lot of packages. Now, there comes a new kid in the block.
Fortunately, it's much easier to write packages for Scoop (aka "app manifests"). You only really need to know JSON, whereas with Chocolatey you need some Powershell and Nuget chops.
