Kali is all about the tools. It is not more secure than the average linux system, actually the opposite most of the time. It is designed for red team hackers mostly. Still neat to poke around with. The same is true for ParrotOS
For a regular user, I'd suggest fedora workstation over Debian. Debian is old reliable, but the out of box experience for the user is clunky and missing some utilities and features. I had a tech friend of mine transition from windows and there were many small things that I hadn't noticed would cause problems.
I still run Debian on many different devices, I like it quite a bit especially when distromorphed with Kicksecure.
There is also Linux Mint Debian Edition which switches the base OS used by Mint to Debian. Out of box experience with LMDE is much more user friendly.
Understandable. For making sure games work I use protondb.com
I haven't had any problems modding games, even using external mod managers.

Ketamine is actually great for treatment resistant depression. Lotta ignorant people in the comments. Fuck the corpos and their nonsense to avoid treating workers with human decency, but ketamine prescribed correctly is actually quite effective.
Behind ublock or behind materialious? I understand what ublock hard mode is. It blocks all 3rd party frames, scripts, and just 3rd party in general. Minor benefit over ublock medium mode but important in my setup.
