ParrotSec V.S Kali Linux in Everything Else Posted June 5 I have run both Kali and Parrot. If you are still getting used to linux and still getting a handle on things from the pen testing side I think kali is the way to go. Most tutorials and breakthroughs are based around Kali. That being said you can still use Parrot and get buy just fine. Personal i run Ubuntu on my pen testing equipment and customize my tool set from there. Most folks will never use all of the tools that are on both Kali and parrot. in the end most of my work is in the terminal since they are all Debian based they are pretty interchangeable.
