Much more stable but much, much older packages at some point. Can you tolerate that?

It is a lot easier these days as Distrobox and Flatpak offer great escape hatches to get newer software when you really need it.

Some of us fiddle with the base OS more than we should. In many ways, I think using something that changes less often is a great idea.

One great thing about RHEL is the documentation. First Red Hat themselves make great stuff. Then there are mountains of third-party materials. Finally, since it changes slowly, whatever issues you are facing have probably been seen before by others and what you find about it on the Internet will still apply.

If you do try Haiku, use Falkon as the web browser. You will have a much better experience than the other Haiku browser options.

If you are a low-end Linux enthusiast, I would also recommend the Trinity desktop. Just as MATE is a continuation of GNOME 2, Trinity is a modern version of KDE 3. I was quite surprised how light and functional it is.

If you want to give it a shot in a VM, the Q4OS distro includes it as a default DE option. If you really want to be impressed what can be done with little RAM, try the 32 bit version of Q4OS.

I don’t love the default XFCE look but the default in distros like EndeavourOS or CachyOS are awesome. It is like a totally different DE.
