Now that you can get latest software from Flathub, there’s really nothing wrong with Debian “stable” except for more recent hardware support that requires newer kernel at the very least (recent userspace drivers will also come from Flatpak if the software like Steam is also a Flatpak). That is, if the stable repo has all you need and there’s no reason to supplement it with external packages.
There are however perfectly valid reasons for going with rolling to get recent improvements, which I for one care about. For example, now that PipeWire is pretty mature, Debian 13 will ship good version and it will serve well for the next 2-3 years, but some 2 years ago it was really important to get the latest and greatest to have good experience - and even early it was better than PulseAudio would ever be, just still improving rapidly, not ready for full freeze.
Other example - KDE Plasma improved significantly from version 6.0 onwards introducing long awaited functionality like fractional scaling, HDR, but also improved stability and general polish. It will only be introduced in Debian 13, one full year after it was introduced.
Lastly, there’s nothing wrong with rolling and it isn’t really “unstable”. Using Arch full time for the last 12 years, I only had like 2-3 situations when update actually broke something and it wasn’t my misconfiguration or a skill issue. Even then it could easily be avoided by using linux-lts kernel. In fact my Debian/Ubuntu installs were much less stable as there was always something missing that I needed (in era before Flatpaks or AppImages especially) relying on 3rd party apt repos, causing breakages and conflicts. I would usually upgrade Debian to testing or unstable anyway, so rolling, but one that’s actually open for breakage.
