EndeavourOS is almost indistinguishable from Arch once installed. On that we agree.
The idea that getting it there has no value is something we can disagree on. You do not have to agree with me. That is not a problem.
I just installed EndeavourOS on a 2020 T2 MacBook Air the other day. All the hardware worked flawlessly after the point and click install. Read the vanilla Arch instructions for that hardware sometime.
EndeavourOS offers a path to installing Arch that is painless and offers a high chance of success. It configures the system well. It is easy to recommend.
Same kernel as Arch, 99.9% of the software is installed from the same repos. AUR is enabled out of the box. Just works. No brainer.
And even though Arch only adds about a dozen optional packages on top of Arch, some of them are pretty useful.
In my experience, just using both the stable and LTS (Long Term Support) versions of the kernel avoids 99% of issues.
In the last two years, I have had drivers fail after an update twice. In one case, my laptop WiFi no longer worked (potentially huge problem as it does not have Ethernet). In another case, the webcam stopped working and I need it everyday. In both cases, I booted into the LTS kernel and was back up and running in under two minutes. In both cases, I tried the more up-to-date kernel a week or two later and found that things were working again. If I only had the one kernel, both of these would have been major issues. With two, they were nothing.
Out-of-date software versions cause more issues in my experience than too new versions cause on Arch. As does not having to work around software missing from the repos. In practice, I find Arch very stable and reliable.
