Hi @road2wisdom, I'm new to steemit, but I've been using Ubuntu for many years. Both Kali and Ubuntu are based on Debian Linux so the commands that you use for Kali will work. For instance they both use apt-get for installing software and updating the system from the command line. I would say that Ubuntu is a general purpose OS. It's definitely easy to use. I got tired of removing malware from my parents pc, so I installed Ubuntu on it a few years ago and haven't had a problem since.
