I have been using Manjaro i3 from an architect installer as Calamares is broken if trying to install encrypted root drive (how does anyone even try a distro that has unencrpted drives maybe only in a VM?) I really like BlackArch Linux, but Manjaro does all the hard work of making i3-gaps just look so damn good with no work required on my part. I like having testing tools to fire up as I'm teaching myself pen-testing, but I also want to run Virtualbox, KVM, QEMU, (B/XHyve and Jails when on BSD/Darwin) and yes even the closed source VMWare. When it comes to having a favorite pen-testing distro, I don't really specify as I can use Ubuntu, Kali, BlackArch, Parrot, Fedora, OpenBSD, FreeBSD and MACOS for testing. Since I'm not specialized enough all the tools I know how to use exist on all the above distros. Of course Kali, Parrot and BlackArch are pre-installed but I have dnf, apt, pacman and brew scripts to install everything I use and more each time I distrohop. Because I'm running on Mac hardware, there are challenges, especially with the MacBook Pro and it's discrete/radeon graphics combination. Kali, Parrot, Debian, Ubuntu, Manjaro and FreeBSD don't play well unless I force the AMD graphics off in NVRam. That leaves only OpenBSD, Fedora, MacOS and BlackArch that can boot and run graphics with both cards active an switching (at my skill level at least). I really like Fedora but wpasupplicant is broken in Fedora30 on my macs, so I have to downgrade to older driver, also the lib files do not work with some of my apps an VMWare is a pain to patch. Manjaro is my perfect dream distro with the i3-gaps wm, but graphically struggles with the MacBook Pro dual graphics. Because I love the workflow and function of i3 I decided I would put Fedora Security Lab on one 2T drive of my laptop and then install BlackArch on the other 2T drive using i3 on each as my preferred desktop. On my desktop I was going with Manjaro as it had Intel graphics. So I re-installed Fedora30 on the second disk of the laptop and then BlackArch on the first drive. After rebooting the BlackArch install and seeing the new i3 setup on the laptop I decided I needed that beautiful desktop on my desktop workstation as well. So far the only issue I have had is that rofi was missing on both installs so I had to install after logging into the desktops. All the roughness of prior to this months upgrades seem to have been polished as well. (simply meaning much of the setup for user permission, such as suders, etc) is setup already and is a cherry on top. I have not been this excited on a first date in a long time. And OMG! it is absolutely beautiful to look at. It is almost too beautiful to be such a useful distro.
