This article certainly does not reflect what I perceive are the best distros and certainly does not elaborate or go far enough to compare the different capabilities with an extended list of other distros in a matrix.
For me, the proposed comparison criteria would be:
-user able to create customized live thumb image with a reasonable amount of time
-user able to update the packages quickly and easily
-user able to find packages of interest quickly and easily
-user able to create own packages quickly and easily
-desktop agnostic. No default desktop. Users must choose themselves which one they want.
-user documentation up-to-date enough to most relevant and trending Linux Distros issues: security configuration for server and non-server alike, desktop, printer, network, filesystems, media player softwares, peer-to-peer softwares, digital-freedom and anonymity.
Arch IMHO is the best. It covers the above with archiso, pacman, yaourt, kde/gnome/other desktops, archwiki covers how to make packages easily and make them available through "Arch User Repositories"(AUR) and installing them through yaourt.
b2im tool for manjaro was the closest and fastest way to customize a thumb-image, but lacked support for customizing an image with AUR packages. archiso can be customized with AUR packages.
Debian Sid is equivalent, but I have classified it as second-best because it takes more time to create & customize a live thumb image especially with an extra persistent partition on the thumb itself. It should be straightforward to do and yet it still is not straightforward to do. live-build takes more than a couple of weeks to customize and it is complex procedure to succeed with both bios and uefi.
Antergos and Manjaro were inspired from Arch. Parrot, Backtrack, Kali, Ubuntu were inspired from Debian BUT ARE NOT DEBIAN. Dare I say a LINUX DISTRO is like a food to be prepared and consumed. If that is the case, which would you prefer depends on your personality. If you prefer to prepare your food yourself, you will go to a grocery store with fresh, unprocessed food products(i.e. Arch/Debian/Fedora), but if you are in a hurry/tired then you could possibly prefer something prepared for you(i.e. Redhat, Ubuntu, Parrot, Kali, Manjaro, Antergos.)
I wouldn't impose my opinion on others to use a particular distro, but I am of the opinion everyone would be healthier by preparing/using the fresh produce and straight from the source: Arch, Debian, Fedora. When you go with the faster food(i.e. Redhat, Ubuntu, Parrot, Kali, Manjaro, Antergos) there are always consequences/constraints, less-recent packages, vendor-lock-in/"take or leave it".
