Android is great if you are on a budget and can't purchase other operating systems for mobile devices. It is also great for installing third-party apps if you find one you like. Although there is a lot of customization options available, this may cause some users to become frustrated if they are unfamiliar with this system.
My favorite way to use Debian OS is to run shared, hosted, network applications for easy segmentation of apps so that when doing work on one you don't have to effect or take down others. I would not use it is for a daily use desktop style OS. For that I would stick to Windows, macOS, or a distribution of Linux that is already geared towards a daily use desktop OS.
The APT package manager is dead simple to use, and the APT repositories contain pretty much every package you can think of. If there's something missing from the standard repositories, there's a good chance a third-party repository can be added to fill the gap.
Debian OS releases are often considered, "boring". But that's a good thing! The Debian developers do not make changes for change's sake and this means new releases are very predictable and intended to cause as little drama as possible.
Debian is such a widely used and popular Linux distribution, that practically all Linux software vendors officially support it.
The Debian community is huge, especially when you consider Ubuntu is derived from it. If you need help with anything, you'll usually find it has been asked before and already has a resolution.
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.
These two operating systems are both great and can totally do everything that we need in our school. The reason we go with Android is that it is cheaper and we have a greater variety of apps available to us. iOS can be a little pricey and it also doesn't allow us to do the customization that we want.
Its has all the needy features that we are looking for plus the support and updates for the OS as well. This means we get all the support and updates in the mean time. Also comparing to others, Debian OS helps us with more security features in built which is also updated over time.
