I can see only a few scenarios where you couldn't use the Linux full time.
The game you want to play doesn't work. E.g. football 2023
The software you need to work professionally with doesn't run on Linux and does not have alternative on Linux. E.g. Adobe suite
All your hardwares are too new that Linux doesn't have enough driver yet e.g. Apple silicone M1,2
If you have none of them, the best reason to use is curiosity. I started my first Linux out of curiosity and now I am a full time Linx user though I still have windows dual boot and a Mac book pro.
