Any of the ~15 most used distros is stable when you learn how to not fuck it up.
As an anecdote:
my Ubuntu and Debian installs used to break twice a year on dist upgrade back then (started with Linux when Ubuntu 12 came out, got it in a magazine). It would cost me a weekend of trying to fix it before giving up and reinstalling the whole dammn thing and re-doing my setup from scratch ...
Then I switched and my arch install has been the same for the past ~10 years with only minor fixes maybe once a year. It outlived the hardware it was on twice.
But every time people keep saying Debian and Ubuntu are stable and Arch is unstable 🤷♂️
