My personal reasons are
- freedom to do anything I want with Os. For example do I want automatic updates? By choise I can enable and specify what kind of updates I want to update automatically.
- customization. Don't like how it looks like a mac or a Windows? Fine change it to look like what you want. Checkout r) unixporn for beautiful desktop environment customizations
- Gaming. Even though not all of the games run on linux, I believe it's the future of gaming. For example some old games that don't even run on Windows 10 run on linux just fine and we have to remember that thanks to Valve, dxvk, d9vk, lutris and wine there are now more games with out of the box experience than ever before.
- Security, stability & repairability. Security updates come faster thanks to open-source nature, stability in a way that you're computer can run 24/7 without any interruptions or errors and if you have a problem with your distro then you can always find a solution to your problem since you own the Os.
