Why would I consider using Linux over Windows in any situation?
It sounds like your use case scenario just doesn't lend itself to Linux very well.
Let's take my situation, for example.
I have a desktop computer with Windows on it, and a laptop with a Linux/Windows dual boot. My desktop is the family computer, it's meant for gaming, typing up things on Word, and use for my non-tech-savvy family. Those are all things that Windows excels at, and most of those things Linux doesn't excel at, at least nearly as well.
My laptop on the other hand is for personal use. It doesn't have as powerful a GPU so I use it for gaming less often, and more often non-triple A titles, which more often are less graphically intensive. Exactly half of my steam library is available and most of my favourite games are in that mix. I also use it for programming in multiple different languages, general chatting and socializing online, school assignments and listening to music.
Almost all of these uses can be covered; I can play most of my favourite non-intensive games, I can still program in Mono C#, Python, and C/C++ (The latter is actually made arguably better by linux, and has some nice IDE's available like
https://codelite.org/ http://www.codeblocks.org and
https://netbeans.org ). My music is covered by
DeaDBeeF, which is a highly customizable foobar2000-like music player that suits my needs perfectly. It also doubles as a music file conversion software, and there's ffmpeg for video file conversion.
I don't think it supports folder playlists, but it's quite easy to add a playlist to your playlist tabs, drag-and-drop in a folder which will automatically add in all the songs, and I believe it has an option to scan and remove songs that don't exist in the folder anymore for when you've made a change.
General chatting and socializing is good, I still have firefox which lets me access web versions of clients that I otherwise might not be able to download and there's discord steam and telegram which are the main 3 that I use. School assignments are actually made a lot easier for me in specific because I'm taking a unix C programming course, but that's unrelated to why I dual booted linux in the first place, and typing up papers and making slideshows is covered by LibreOffice, which is a surprisingly good alternative to the Office line of products if you give them a chance. I can't name any functions off the top of my head that Libreoffice Writer has that Word doesn't, but I believe the Libreoffice powerpoint equivalent is lacking in some of the features that Powerpoint has.
My use cases are generally covered by it, and if I think that I'm going to end up needing something windows exclusive that day (Like visual studio, which as far as I know can't be run in Wine) then I just boot up in Windows instead of Linux.
Just know that Linux absolutely is not for everyone. By the sounds of it, McJob, it just doesn't seem right for you. You have too many uses for Windows that include windows exclusive programs, having Linux dual booted would seem like a waste of space for you. For other people, a dual boot can work nicely (like in my case), and for yet others, you can get away with exclusively using Linux if all your windows-exclusive needs can be run in Wine.
The only thing it's really lacking imo is something like Paint.NET. GIMP is alright for general editing but if you need to actually like, draw a diagram it's really not that great because of its lack of a shape drawing tool. There are solutions but they're not as nice as Paint.NET is.
