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.
For the longevity of a product and intuitive design. But it is a matter of opinion, and if you are more comfortable with Windows, then stay with Windows.
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.
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.
macOS just makes sense to me. Each OS has its pros and cons.. macOS works for me. It's well designed, intuitive, and efficient. But it's not cheap... well, macOS is basically free, but you need the hardware to run it, and the hardware isn't cheap. Pick the right tool for the job and for you. And even though macOS may not be thought of in an enterprise environment, it works remarkably well if configured properly. Tools like DEP and ABM from Apple enable device management and lock them to the company. Use an MDM like Jamf to push policies and packages. Jamf can also manage accounts and authentication. JumpCloud is another great product for account management. Although it might not be all included in the box, with the right knowledge, you can build a robust and versatile enterprise Mac infrastructure. You can even do zero-touch deployment in most cases with the correct setup. And Apple employs engineers to help you get it set up right.
