I did find a nitpick:
For example, the Core edition of Zorin OS 16.2 (the most current version released October 2022) is still running Gnome 3.36.1,
Zorin OS 16 has been using Gnome 3.38 since its release.
From my terminal on 16.2:
╰─ gnome-shell --version ─╯
GNOME Shell 3.38.4
I feel a little bit absurd posting a minor nitpick against a favorable review but... A scientist first. Facts are facts.
Over-all, I found your review to show little slant or bias. You pay fair attention to each feature such as Snap, Flatpak, XFCE or Gnome without editorializing or injecting opinion.
And there was something I found intriguing:
Core is the main edition and comes with the Gnome DE. This isn’t your father’s Gnome, however, as Zorin has heavily customized the look and feel. In so doing, Zorin avoids many of the criticisms that are often leveled against Gnome.
...At the same time, however, because Zorin relies on such a heavily customized version of Gnome, most users won’t really notice that it’s behind. In fact, some of the features that have just made it into Gnome 43, such as accent colors, have been in Zorin’s customized implementation for some time.
You noticed this!
Many do not. Most often, the Gnome on Zorin OS Core is treated as just "Gnome" with a Zorin OS theme - A "reskinned" Ubuntu.
Which is not the case. That you examined in detail and noted these changes is high praise for your review.
I will end this post with my more normal cynicism.
My own opinions of Snap, Flatpak and Gnome are well known and often vehement. I usually hold little regard for PopTech articles that push an agenda or motive, leading the reader (user) to conclusions and are often unbalanced. As unbalanced as my own opinions.
That your review was bereft of all of that was a breath of fresh air.
Thank you for taking the time to review Zorin OS thoroughly and neatly. And for sharing it here - it lifted some spirits on this side.
