No big difference between those two methods of install. You get the real medal when a random upgrade breaks some software and you are able to track down the issue and corresponding solution(s).
Endeavour Os was the best thing I ever used. Easy to install, out of box is minimal but sufficient. I traded my Linux Mint to be able to customize my workflow, look and feel.
My current issue is that I can't remote into the machine at all beyond ssh. Any attempt at a session just refuses to work no matter what guide, fix, video, forum post, etc I follow.
I don't use Arch but if I did id probably go with archinstall. I don't see the point in going from scratch unless you absolutely need to. I could care less about bragging rights for installing an operating system lol.
I just don't bother going for archinstall when regular installation "from scratch" takes 5 minutes (or 15, if you do it the first time). It is not scary and extremely simple, contrary to memes. Besides, it makes you understand the processes involved.
Archinstall is just a little, nice helper to shorten and simplify installation even more.
NixOS is the new Arch.. (cat, meet pigeons) Unfortunately It doesn't have as much basic training as Arch did (which archinstall obviates, not that I think this is a bad thing, it's time is here), which did so much to improve community. Unfortunately NixOS's doco is woeful, while ArchWiki is gold standard.
I say this as an ex Arch type who moved to Fedora, now ublue-kinoite, waiting for Nix to mature enough to daily (although I do have a T440p with 3 boot drives not doing much, hmm)...
Yeah nah, arch has an actual use case for normal users - it's just the same old Linux with the most recent packages.
Nix and guix simply don't work as distros for regular people. They're made for scientific and corporate applications. They add a huge amount of complexity in order to solve problems you don't have.
Nixos is like rust: hyped into the stratosphere by people who don't use it

I'm running guix in fedora as a PM. You get most of the benefits, and can still use other PM's like npm without crying for a week first. Although imo guix works better in that scenario since you can just "guix install X" and then use X like any other binary.
I tried so many distros in the last decade, but I recently had to start with a fresh setup again and I went with Linux Mint. I think it's the most underestimated workhorse you can get. Everything just works, tons of help online if you need it and instead of tweaking it forever you just get work done.
I totally get that and I used to do the same. Maybe this community is different but on some online communities people kind of looked down on mint and pretended it was only a beginner distro.
I love arch but I actually haven't used it since before they added the arch install. I can't imagine how much easier it is cause it's still the terminal. The "manual" install was easy as hell
