After the first year fully immersed in Linux, I would say most would agree with that statement “One can turn any distro into another”, at least in what matters to them.

To any newcomer I recommend to choose the environment (The tendency is for the tech-minded that come from Windows is to choose KDE, less tech-minded or straightforward thinking choose Cinnamon and exclusive Mac and Android users tend to choose Gnome).
The second thing to select is your stand on Stability vs Cutting edge. The rest of features are far, far less relevant and you can easily fine tune to your like and these is what people mean with that above statement (even the environment and stability could be customized too but most would not be able to do it).

At the end, the distro is a choice where you pick the first two parameters and the exact distro you pick is more based in convenience and/or philosophical criteria.

My case: I played with 5 environments and KDE is my cup of tea. Then, I choose a distro in the middle of the road with updates (OpenSuse Tumbleweed) and while extremely happy two updates within 8 months gave me two hiccups (nothing mayor) but I decided I needed more Stability. While I consider Fedora to be the “best” distro by just a hairline, since it has the most resources, but philosophically I am against due to IBM being its main backer, not to mention, US may cause problems “exporting” in a near future… yes you can fork, but you still being dependent in the main source for a while, not to mention supporting IBMś aims. So I am Debian (MX Linux actually) all the way now. However, I recommend to most Mint (for the most conservative) and TuxedoOS (for those looking for a more contemporary look) to most people I encounter.

The rest of distros, or are just niche (for instance Deepin and Kylin cater for Chinese language, Cachy for gamers, etc) or are distros with far less resources to do it properly, but I passionately applaud their existence since they all are contributing with the good cause.
