My best friend and I have been in game dev for decades, and we both switched to Linux a few months ago (he wants to switch careers to military tech), and we first got our feet wet with the usual Ubuntu and Pop (same as OP, we consulted GPT that recommended it).
Because we've been in tech for so long, we quickly made some realizations.
All distros use the Linux Kernel, so whoever commits most changes to the kernel has effectively the most power to shape the future of Linux. We checked the
git contributions on the Kernel and found that most are from hardware manufacturers like Intel, Google and AMD, which makes total sense as they support a plethora of hardware products (ARM processors, Android phones etc).
In terms of Kernel commits made in the interest of Linux as a desktop operating system, there are two relevant contributors - Debian and Red Hat.
Ubuntu and SUSE used to contribute significantly, but number of commits has waned over the years as their support shifted to cloud and hardware.
Debian has no money behind it. Not true, I lied. Yes they have sponsors and donations, but it's a volunteer effort (a huge effort though, massive really).
Red Hat on the other hand is a billion dollar business. Nobody puts more money into Linux as a desktop OS than Red Hat does. None of us here on GAF are going to install Red Hat though, because it costs hundred of dollars.
Red Hat pays for the development of Fedora, which they use to develop the newest tech and prove its reliability to the average user (you and me) so that it eventually trickles down to Red Hat for the business consumers (IBM, military etc). So you got full-time engineers working on Fedora, making commits to the Linux Kernel and building the most polished, newest Linux OS. My friend and I understand why Linus Torvalds uses Fedora (or used to before Linus switched to Mac lol)
Money pays for smooth polish and bug fixes. A team of full-time Red Hat engineers with 200K salaries simply out-compete the hobby distros (Nobara, Bazzite etc) maintained on GitHub as a side project for programmers.
That's why I recommend Fedora, as an avid gamer and dev.
