What do you like best?
Most of the tools from Kali, but on a much more stable base and with more current versions of kernel non-pentest software. Also, snapd is installed by default, giving you access to software from the Snap Store.
Like Kali, chances are extremely high that your networking hardware will work out of the box (critical for wireless on a MacBook).
Polished look and feel, easy install process, btrfs by default.
What do you dislike?
Not much. The fact that it's Debian- rather than Ubuntu-based means that adding PPAs is a little more difficult (use sparingly - while not nearly as brittle as Kali, using Ubuntu repos on Debian can still potentially cause problems), in that you have to manually add them rather than a simple "sudo add-apt-repository ppa:whatever/whatever".
Limited Mate desktop experience compared to Ubuntu Mate, but even the Mutiny look and feel can be replicated with a little work.
Being Debian-based also means that lxd isn't available in the repositories, but you can install it as a snap. Nodesource and Docker repos (faking another distro's version name) and keys must be added manually.
What business problems are you solving with the product? What benefits have you realized?
Pentesting (obviously), as well as development and virtualization/containers. Performs better than most other distros, even with a ton of software installed.
