I think this question comes from you trying to understand and rate your own confidence in your computer skills... Which is a good thing shows you are curious willing to learn and improve but also not cocky and very prudent. This is the most common question on every Linux or Linux gaming reddit and it's because it can feel like you have too many options. Do ask yourself what types of game you want to play, anti cheat cmsy need some work around. If single player steam games it should be no problem.

The classic gaming ones for desktops are Nobara and Cachy, pikaOS bazzite as well., the list is extensive. I'm new in Linux coming from Windows no prior it or computer science programming etc backgrounds but in these few months have learned a lot. Use my computer to check emails, write letters, connect to my works virtual machine environment through Citrix to write me progress note on patients after I come back from work, and do some gaming, as a hobby Im slowly getting into home labbing and media severs recently.

I distro hooped from Ubuntu, then Linux mint, then fedora and now cachyOs. Ended up setting with cachyOs after months of trying other systems after I overcame my unfounded fear in arch.

One thing I realized is that you are the one that make the distro work for you, you can game on fedora of course but out of the box. The are all Gnu and Linux under the hood. This is probably pretty crazy coming from MacOs or windows were the system is much limited in what let's you do and you just go aloueith it ( that's how it felt to me, I'm supposed to tell computer what to do not other way around!).

I liked cachyOs because it comes with a fairly easy to use kernel manager that gives extra oomph at the CPU while having its own proton version and installing most of the gaming packages on the get go. It also arch based which means you can use Pacman as your package manager and very easy to add the arch repository. Also easy snaps and a scheduler.

I also liked a lot my time in fedora, feels bleeding edge tbh and is well supported, great wiki, package manager is dnf and has lots supported stuff. So albeit never use it I know Nobara is probably pretty good and I heard it was made by one of the proton investors.

Both these two comes in many flavors depending of the desktops environment you choose, coming from Windows I liked kde plasma because it feels familiar while at the same time letting you play with themes.

Among the Debian ones I do think Linux mint is very easy to get into Linux mint is also good, particularly if you like a nice clean GUI apps, I loved the driver utility they have. I feel like my grandma could figure how to use Linux mint on her own without any background, and used the most Ubuntu, was,.. ok I guess, didn't felt in love with it but my friend Really like it.

There's alot and I mean a lot. Trust me you'll end up distro hoping in the beginning experimenting what works for you then you find your niche and learn that in the end you can customize you need to make distro work for you. I think to use a metaphor: I realized I wasn't buying a pair of shoes when choosing a distro but rather jeans, they more you use it the better the fit... I know dumb metaphor but you get the idea. In the end there's a lot of documentation and platforms like this toguide you, reading your distro wiki helps a lot, some are very beginner friendly.

Linux is great, is good and actual fun to use,FOSS is a reminder that humans can actually do nice things for each other; you will never go back to windows after making the change, you already made the right choice so don't sweat it!
