Windows 12 could require all users to get punched in the face to log in and most people would say, "Yeah, it sucks but it's better than spending $1,800 on a Mac. Plus my video games..."
General web browsing type tasks are solid, text editing/note taking works. Videos and audio (including Spotify) work. Steam and games generally work (even most windows games through Proton).
What else does ones daughter need for school? She’s not video editing or creating music (two use cases where you may need windows or OSX; art is more or less covered through blender/Inkscape/krita)
Mint or Manjaro are easy to install and setup and come with good defaults that should be pretty easy to navigate for someone new to Linux.
In my experience, kids do these things all the time for school projects.
EDIT: (I don't mean this in a mean way, just to say that people who care a lot about being able to play specific games probably still won't be satisfied without a Windows box).
Would you say it’d satisfy for twitch shooters?
Sadly looks like a lot of the top 10 are in "Borked" status, though.
50% of them, but 2 of the 5 broken games are known to be buggy in general (New Worlds anyway, PUBG was years ago, no idea how it fares nowadays so maybe I'm wrong) so dunno how much of that is Proton's fault. The two gold ones seem hit or miss: many people report they work, but some people have issues.
Still, a lot of AAA games work perfectly (eg Sekiro) and many games I play even have native Linux versions (Crusader Kings 3 being the main one, I'm hoping with the steam deck more devs will release Linux versions but maybe that's too optimistic) and most of the indie games I play work well, so for me, I've been pretty happy and haven't looked back.
