It's pretty much exclusively about the update process for me. With fixed-release distros, you typically only have to actually pay attention, read news posts etc. before updating to a new major version, which in case of Ubuntu LTS happens every 2 years, which is a lot fewer opportunities to fuck up than Arch's rolling release. Not insurmountable if you're something of a power user or willing to put in the work to learn, but hardly the first choice for someone asking for an entry-level distro.

But if you’re gaming, I think you should be on the latest kernel possible, so a rolling release(Fedora) or bleeding edge(Arch). Latest Ubuntu derivative(25.10, soon 26.04) is fine but not ideal. It’s the main reason SteamOS is also based on Arch.

Ubuntu's HWE kernel is just fine, even for LTS users. The only time it might not be enough is if you buy bleeding edge hardware. IME, the actual issue with Ubuntu for gaming is that sometimes you'll need newer mesa packages, which needs to be acquired separately from the kernel, usually via PPA. If you're playing newly-released AAA games, that does come up occasionally. e.g. I started using a mesa PPA when I got Elden Ring. Though I'm not sure if even that is necessary if you use the 6-monthly Ubuntu releases.

So yeah, if you're that kind of gamer, Arch probably is a cleaner or at least equivalent solution than Ubuntu.
