Manjaro, because it’s rolling release and it’s built on Arch, only the necessary stuff is installed (including a desktop environment), you can set it up with just a few clicks, and it works out of the box, and even proprietary GPU drivers are easily installable with mhwd. Stable and reliable.
In case anything breaks, there’s quick help on their forum, which (when it happened to me once) outperformed customer support of proprietary software.
It’s been my daily driver for almost 8 years without any major issue.
So in short, robustness, rolling release, simplicity, community.
Edit: I have to add, my use case is for a desktop PC for software design/development + a little gaming.
In my opinion, social media is extremely harmful to society. Fediverse has implemented some proper moderation, while those more popular platforms tend to amplify what makes this world crazy (and eventually completely destroyed).
If there’s one reason why it’s not okay that those platforms are more popular than the fediverse, it’s that at least the Fediverse has the chance to properly moderate content, while on those platforms it’s either unmoderated, or even worse, the quality content is oppressed.
