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.
IBM AIX is a very powerful and extremely stable operating environment. It is well suited for applications that are business critical and cannot tolerate outages. It is best used to address large enterprise level application needs where stability and scalability are of paramount importance. IBM AIX is less useful for small enterprises.
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.
A lot of the built-in commands have not been updated in years. If you're used to some fancy CLI options in Linux, you may be out of luck with AIX.
Out of the box, you cannot run open-source Linux utilities on AIX. There is a toolbox you can install, however, it's not the same versions as you would get in different Linux flavors.
Tab completion for files and Up arrow to re-run previous commands don't work out of the box without running a Korn shell. A small annoyance, but one that catches me every time!
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.
When compared to others, Debian runs smoother and faster and has great support for feature set with it. Even installing other supporting tools or IDEs for development work is pretty easier. With few simple commands and a good internet connection all the debian packages from the Internet can be easily fetched and installed on you systems
Standard Linux distributions which are used more as commodity servers do not offer the ease of scale and growth that we see with our Aix implementations. IBM owning the HW and SW portions of the stack allows for tighter integrations and better performance windows.
Due to it's low resource requirement, we are able to run more applications on less physical hardware
Because of it's versatility, we are able to learn Debian well and run our applications off of the same base operating system. That saves time and expertise requirements.
