I exclusively use Linux on my PC, including for gaming, and have so for ten years.
It's... A mixed bag. Getting to use Linux instead of Windows is the great part about it. The totally different philosophy, a convenient way to install apps, no mess with device drivers, easy distro-hopping and reinstallation, a way to free yourself from the vendor lock-in. If you haven't tried it, but think you'd enjoy it, I'd strongly encourage you to try it.
Gaming works but isn't pain-free. I can enjoy a lot of games, and SteamPlay is fantastic. But there's moments like when I have to redownload all 20GB of Transport Fever 2 on GOG after an update was released, because there is no GOG Galaxy on Linux. Last week I was trying to get Trackmania 2020 running with a friend. The gameplay worked fine, but the Ubisoft Connect overlay was totally bugged. Whenever I opened the overlay, the game would then refuse all keyboard and controller inputs until I restarted it. Since the party system uses this overlay, I couldn't play with my friend because of this bug. And our entire evening was wasted reading through forums and ProtonDB to try to fix the problem to no avail.
I encourage you to take a look and see for yourself and try it, I will never go back to Windows, and it's free so you're not losing anything by trying. A passion for fixing things yourself helps. And it's not all sunshine and roses. But good luck, and we'll do our best to help you if you need it.
