1. Pre-Installed Security Tools: Kali Linux comes pre-packaged with hundreds of security tools used for information gathering, vulnerability analysis, exploitation, password cracking, forensics, and more. This setup saves time and effort in installing and configuring each tool individually, allowing you to focus directly on learning and testing.
2. Optimized for Ethical Hacking: Unlike general-purpose operating systems, Kali Linux is tailored to the needs of cybersecurity professionals. It is structured to maximize performance for security tasks and streamline workflows, offering features like custom kernel configurations optimized for penetration testing and streamlined updates for security tools.
3. Learning Environment: Kali Linux provides a safe environment for learning and experimenting with cybersecurity techniques. It allows you to practice ethical hacking techniques without impacting your primary system, and it’s also highly customizable, so you can modify it as needed for different scenarios.
4. Community and Support: Being one of the most widely used penetration testing platforms, Kali Linux has a large and active community. This makes it easier to find tutorials, documentation, and forums to troubleshoot issues, learn new skills, and share knowledge with other ethical hackers.
5. Portable and Flexible: Kali Linux can be run as a live system from a USB drive, in a virtual machine, or even as a persistent installation on dedicated hardware. This flexibility makes it easy to carry Kali Linux with you and run it on different systems without installation, enabling you to conduct penetration tests in varied environments.
6. Industry Standard for Certifications: Many cybersecurity certifications, such as the OSCP (Offensive Security Certified Professional), expect familiarity with Kali Linux because it’s commonly used in professional penetration testing. Setting up and working with Kali Linux helps you develop practical skills that align with industry standards.

In summary, setting up Kali Linux is crucial because it equips you with the tools, environment, and community needed to develop, practice, and refine ethical hacking skills—allowing you to work securely and effectively while preparing for real-world cybersecurity challenges.  This package would have all the readymade stuff for you to straightaway start your process.
