Winget is from Microsoft for one (and already installed with Windows). It basically just downloads the regular windows installer and installs it like usual without the need to click user feedback prompts. Scoop is more of a package manager.

With winget, one nice thing is you can even update packages not installed with winget originally. You can see which apps on your computer have updates available with a single command.

It’s great when you’re updating someone else’s computer they haven’t updated random things in years (typical windows users).

Scoop essentially uses portable apps and everything is in your scoop folder which is great.

I use both. Scoop first and winget for everything else. I use winget to update Libreoffice on all our work computers (because the devs won’t work on auto updates).

I felt like winget was too limited. When I last used it it didn't support installing multiple apps at the same time. scoop feels much more like traditional *nix package management to me, which I like.
