All of which is just to say that it’s (almost) ill-advised to prefer a new project over a well-established one. Only after a (relatively) new project receives mass adoption, like what we currently see with Bazzite and CachyOS, does it become somewhat of a safe bet.
If you should prefer an established distro over a new one, how is the new one ever going to get mass adoption? And let's be honest, if a distro is a one man or small team project, mass adoption is no guarantee of longevity.
