When comparing Kali Linux vs GNU/Linux, the Slant community recommends GNU/Linux for most people. In the question“What is the best operating system for a developer?” GNU/Linux is ranked 1st while Kali Linux is ranked 9th.
Ranked in these QuestionsQuestion Ranking
Pro Better than ParrotOS, BackBox for hacking purpose
Contains too many tools for hacking. Those tools are not already included in BackBox or ParrotOS.
Pro Standard pentest tool set
Pro Live session distro used for forensics
Pro Lots of development tools available
Pro Most likely also your deployment target
Makes testing while developing easier. According to a September 2014 study by W3 Techs, *nix based servers are used on over 2/3 of websites.
Pro Access to really powerful terminals
Pro Large percentage of Linux users are developers
Pro Package managers
You can install any library or package that you need (gcc, php, node) with just a couple of commands in the terminal.
Pro Most software is open source
Pro Most Linux distributions are free
Pro Follows the UNIX philosophy
The UNIX philosophy: 'Write programs that do one thing and do it well'. Since Linux itself follows this philosophy then it's very easy to start creating scripts and programs.
GNU/Linux handles desktop sessions differently than Windows. Users may customize their own sessions; in fact, a single user may use different desktop environments for different login sessions.
Pro Familiarity with Linux is often required from a developer
Many university computer science programs are based on Linux and in any case, you will inevitably be dealing with a Linux box of one flavor or another someday, be it a server (most likely) or a workstation. The languages and methods used in the Linux/Unix environment (e.g., bash, C, C++, Make, etc.) are very commonplace among developers and are to the computer side of the discipline what the English language is to the human side of it: the common language.
Pro A wide variety of distributions available
With a lot of variety, one can use the distribution that fits the type of work best because of the many choices that are given, instead of just one.
Pro Works great on older hardware
7-10-year-old Dell laptops can run Unix or Unix-like OSes very well, where Windows would grind/drag/vomit.
Nice, developer-friendly environment.
Pro Choose any type of desktop environment (or none)
Most Linux distributions support a range of desktop environments, be it plain old X, a tiling window manager or a fully fledged mammoth desktop like GNOME or KDE.
Pro Extremely fast
Can be made even faster by going GUI-free or using a lightweight window manager.
Pro No telemetry, unlike Windows
Pro Lower chance of data loss
Linux has very few viruses. So there's almost no chance of getting infected by a virus and thus losing your data including your important programming files.
Pro Hardly ever crashes
And if it does you can often drop into console and fix the error before returning to desktop.
Pro Sometimes it "just works"
Sometimes Linux tends to just work with little to no effort or troubleshooting required. Most of the times it doesn't, though.
Pro Get works done
Get near each and every work done within the command line or terminal, it makes everything so simple as compared to any other os
Pro Isn't "locked down"
Windows and MacOS tend to restrict what the user/developer can do with their PC while Linux empowers the user/developer so they can do whatever they need/want with their PC without unnecessary restrictions.
Con Not intended to be a daily driver
This distro was written for pen testing and security work. It is not meant to be a day-to-day OS (unless that's your job).
Con Very old packages
E.G. Firefox's current version is 61 but Kali linux consists of its 52th version. Though kernel is not that old.
Con Issues with drivers if your hardware is not officially supported
Con Maintenance can be time-consuming
Con Hard to get used to working in the terminal
It might be a challenge when trying to get used to using the terminal a lot to get around certain things
Con HiDPI support sucks
Many developers work on apps that should work on HiDPI monitors. In most distros, HiDPI simply suck on Linux, and making that work is a nightmare.
Con Steep learning curve
Con Too much customization
To get features on par with OS X, you need to research packages, install them and configure them. Even then, it may not be as good as OS X.
Con Less and worse professional software is developed, due to the low user base
Depending on what type of work you are doing, you may find Linux software lacking compared to their Win/Mac counterparts.
For example in game development, tools, like Unreal Engine or Unity, usually lack in quality or novelty compared with Windows. Having crashes or bugs that aren't fixed for a while.
Con A wide variety of distributions available
With a lot of variety, one cannot deploy to a single system and has to prepare for a bundle of distributions, instead of just one.
Con Low user base to develop to
Linux can develop to any system with the right tools. Mono allows development to Windows. Python and Ruby too. C and C++ can be developed to Windows.
