What's the best linux distro?
There is no best Linux distribution, Every distribution has it's own use cases that it is best for.
If you want me to help you find the best distribution for you, please share what you will mostly use it for.
I plan to mostly do gaming
You can play games on any Linux distro, however there are some custom tailered ones. The choice depends on your specific needs and requirements. Popular linux distros for gaming include:

- Drauger OS (most popular and actively maintained)
- Lakka (lightweight Linux retro gaming distro that turns your computer into a retro gaming console)
- Ubuntu GamePack (gaming distro based on Ubuntu, re-installed with games and all the gaming software you’d need, including e.g. Steam)
- Fedora Games (distro (spin) based on Fedora that includes a lot of installed games available for Fedora)
- SparkyLinux – GameOver Edition ( lightweight Linux distro with a special release for gaming)
