Can I tell you off from Arch Linux?

There are around three Linux families to choose a derivative Linux OS from,
some are more obscure ones and then some really obscure ones.
Choose one of the Linux family OSes and choose the most popular derivative of that one.
So for example Aurora is a derivative of Fedora, which is a derivative of RHEL (derivative-(in)ception).

The reasons to choose derative OSes and not one of the basic main three is that:

1. The Linux derative OSes have bells and whistles build on top of the parent OS. This is especially true for the extremely bare bones Arch Linux, that will throw you back into 1985.
2. And this is most important… community support! You will at some point have issues and a forum where developers and experienced users can help you out are a godsend. Derivatives tend to have better community support than the bare bone ones. I’ve experienced this with the Arch Linux community. I’m not sure if Debian or RHEL communities would haved fared better, but to me this community felt like having a conversation with a real life Sheldon Cooper. I am really thankful for the excellent expert level help I did get there, but I will not go there back again. And I don’t know if I even can, because the last time I was there, I got banned for a third time.
   I’ve had great experiences on the Ubuntu, Linux Mint and Manjaro communities. Other communities from less popular Linux OSes have been too small in my experience to get help on time.

For Debian, the most popular one right now is Linux Mint, a derivative of Ubuntu (derivative-(in)ception). It used to be Ubuntu, but Ubuntu tends to take big moves and risks that don’t always pay off.
Linux Mint I consider to be the safe option for beginners.
Debian is known for stability.

For Redhat it’s Fedora. I haven’t used it that much.
Redhat is known for good security.

For Arch it’s Endeavour OS and recently Cachy OS.
It used to be Manjaro, but they fumbled a lot on security issues.
Arch is known for having the best documentation,
and the largest amount of software available,
especially made by fellow users,
and if I may add myself, having the best package manager.

I still use Manjaro myself, because I don’t feel enough need to switch to a new one,
and I like the community there.

Linux folks used to be much worse about gatekeeping, but even 20+ years ago when I was first starting out, there were always decent folks among the techie dumbfucks.
