First off a warning, give this distro at least 12GB. First try I gave it 8GB and it was so tight on space I couldn’t even run updates. If you’re looking for security tools, it got em… tons of them. As far as looks go it is a pretty basic LXDE setup, nothing special. It is a rolling release based on Debian testing so it should be pretty stable. Overall I wouldn’t use it as a daily driver but if you’re trying to do some security testing, Kali is the way to go.
