It’s not user-oriented the way the distros based on it are. apt is mediocre and slow compared to a lot of other distros package managers.
The out of date software is really important for new users for one big reason, and that’s hardware compatibility. Arch Linux, especially with AUR DKMS, can work with basically anything supported by Linux. Debian will struggle with anything sorta new. Having on old kernel, like Debian does, is one of the worst things a distro can do, for performance, for compatibility, and more.
Their software is also actually super duper out of date, too. To the point where KDE on Debian and Kubuntu is several versions out of being supported. A lot of software developers are sick of people reporting fixed issues because the user is using Debian, so they tell them to use a more up to date distro.


Stuff based on Debian, like Mint or whatnot, generally also “just works” just like Debian would, while also having more up to date software with their own repositories, and more user friendly software to automatically do stuff with GUI’s.
