In the last 10 years I've used linux from time to time on my personal PC, mostly used for gaming and web browsing. Always switch back to Windows, because it was not ready for my use, mostly due to gaming.
3 months ago I got fed up by windows forcing on me the connected account and installing crap by default, so I tried a few distrib and stick to ArchLinux, this time I didn't switch back to Windows, and for now, I don't intend to. I don't play online "competitive" FPS anymore, which tend to not work well on linux because of anti cheat. Linux compatibility improve every day for gaming, it has been mostly flaw less for the past 3 months. With the steam deck, compatibility greatly improved, and it's getting better everyday.
I feel like Arch is more snappy than Windows, everything feels more responsive, and man update are so quick, Windows takes forever to update... And I like having more controls of what my PC is doing for better and worse.
Do a list of what you want and don't want for your usage, then try some distrib and check if it fit your needs or not.
Yes there is, but it's a pain to setup licenced test environment, and with only 16 free licence you don't go far.
I think it's a bit short sighted to say that Rocky and Alma doesn't contribute back to RHEL and linux in general. From what I've seen about the ecosystem around REHL, it seems that they need each other.
