Which distro for gaming only?

Hello, I plan to build a PC for mid gaming and plan to install a Linux gaming distro on it. I will only use it for gaming. I'm familiar with Linux, I used (or still use) Debian, Ubuntu, Kubuntu and Arch.

At first I wanted Garuda OS and then I heard a lot about Bazzite and it got me wondering. I own games on all the big platforms (Steam, GOG, Epic games, Blizzard, Ubisoft, EA,...) and want to use them with Linux.

There's also the GPU problem. The one I plan to use is a MSI GTX 1660 Super and I know that nvidia drivers are proprietary and a pain to make them work on Linux.

Any advice, personnal experiences or tips are welcome. Thanks
