If you take those distros, and add all 300 tools from kali linux, you end up with kali linux, just shittier, and maybe based on a different OS, so probably a different package manager and thats about it (at that point)
Seriously, I'd be more impressed if you built a bare bones OS that included tools for compilation and netcat. That's it. Make me the tiniest, most compact OS ever. I mean it's been done before but I'd still like it better than you apt-get *'ing 300 times on a fresh ubuntu install.
Also Ubuntu Debian and Mint are all fundamentally the same OS, Js.
