There’s always Bazzite’s vanilla KDE cousin, Aurora: https://getaurora.dev/ It is essentially the Fedora KDE spin with way better hardware support and QoL features.
But Bazzite isn’t really a distro in it’s own right anyway, it’s an unofficial Fedora spin that gets updates pretty much immediately (<24hrs) from upstream. It kind of “solves” a lot of the issues with most gaming distros.
I’d highly recommend both to new users as well, as they are immutable (like the Fedora Atomic Desktops) and make it a lot harder to completely mess up your install while you’re still learning.
Except the one Marques has can go 15mph, or about 24kph, almost twice that of the one in the article.
