Debian is very well suited for application servers, web servers, file servers, hypervisors (personally, we use Proxmox for some hypervisors and this is based on Debian), and much more. It can run on various CPU architectures and scales well from large to small. We have Debian DNS servers running on Raspberry Pis, and large application and database servers running on powerful Debian installs in our racks.
If you want an OS that is rock solid, easy to manage, and predictable, Debian might be the OS you're looking for. The official packages are generally far from being bleeding edge versions, but this means that you are using packages that are battle tested and will not break compatibility at any point during its life-cycle. This, to me, is one of Debian's core strengths and a good reason for recommending it to others.
On the flip-side, the lack of up-to-date versions of various packages may be an annoyance if you actually do need to be using the latest version of such a package. If you need to be using more modern versions, you will need to remedy that yourself or look at an alternative distribution. Ubuntu may be worth a look, in this case, being that it is basically Debian with newer packages and some minor differences here and there.
Personally, I would not recommend Debian for a graphical desktop OS. You'll nearly always be better off with one of the Ubuntu flavors for a modern desktop with all the bells and whistles you'd expect with a GUI desktop.
Indeed, it's super. OS makes it the most feasible item right now on the lookout. It's smooth, and it will not slack even following 3-4 years settling on it. A wise speculation choice for an innovation.
Debian is one of the most well-thought-out, logical, and intuitive Linux operating systems you can use. Configuration, package management, file system layouts, etc, are all based on many years of usage, and it's very rare to find anything surprising or confusing in everyday usage. Package management and updates are handled by APT in such a way that once configured, you can almost guarantee your system will behave as expected for the lifetime of its service. Top-notch system integration provides all the tools you'd expect from a modern Linux system, with all the stability you demand from a demanding server OS.
In all likelihood, common users will either already have experience with iOS on their iPhones, or will pick it up quickly. The UI is generally simple and mostly visual. Power users, on the other hand, may feel constrained by the inherent limitations built-in. Root access, terminal commands, and deep customization are not really to be found here.
Lots of help articles online for just about everything under the sun. I have never personally had to engage Apple's support team to comment on their helpfulness.
iOS is way beyond Android in terms of centralized management. It is way more fleshed out in terms of features, and Android management has all but been abandoned at this point. iOS is still behind Chrome OS, particularly in an educational setting, but there are genuine tradeoffs that might make it a better fit for a given organization, and in fact, we do regularly deploy both iOS and Chrome OS devices.
