I’m planning to switch from Manjaro to pure Arch, but I really like the easy setup Manjaro provides. Are there any guides, wikis, or personal tips to replicate that setup on a fresh Arch install? Looking for something that covers the essential packages, configurations, and tweaks to get a similar out‑of‑the‑box feel. Thanks in advance!


Pure Arch isn’t going to give you what you want. EndeavourOS is probably a better option. Nice installer, a relatively kind and helpful community on their forums, and you can use the Arch wiki to fill in the gaps.

I’ll second this. I left Manjaro for EndeavourOS a few weeks ago and, so far at least, the experience has been flawless.
This or one of the other “Arch but easier” distros like CachyOS or Garuda Linux. I’ve been running Garuda happily for about 4 years now, and recently put CachyOS on my laptop to play with it and so far it’s been great too.
