Stable has nothing to do with outdated packages.
That’s a personal decision by a distro.
Fedora is a stable distro because generally the packages stay on the same major version throughout the version, however they have a list of exceptions for certain applications that should be updated for security or perhaps they don’t follow a major/minor/bugfix release and it’s bad practice to hack together your own versions.
Fedora rebases it’s packages every 6 months, so it’s never left far behind.
It all depends on what you actually want to do.
I have a computer connected to the TV with Chimera installed because that’s SteamOS 3 with emulators preconfigured and is completely couch + controller friendly.
My laptop has Fedora because it’s up to date, but everything is tested before release, and all upgrade paths are automated unlike Arch which burnt me in the past with breaking changes.
On my Pi’s I have Diet Pi, which is Debian but has images for each of the different ARM boards and has a bunch of scripts for setting up print servers, Home Assistant, etc. I want Debian for it’s slow unchanging nature there.
On my desktop, less so.
But underneath they are all Linux, and they all behave in very similar ways, it’s all about the initial setup.
