And ubuntu comes a bit bloated out of the box. At least for a "normal" power user that knows how to install the things he/she needs.
I'm also impressed from the support in the packages. For example, you need a new fancy editor? latest version? Atom, VS Code? sure, just install it from the package manager. Maybe need the latest of node.js? or vivaldi browser? It has them. It's much more complete than I thought. No need to look for .deb packages on anything.
And last, I won't have to change anything in 6-12 months when a new version comes out. There are no scheduled releases from what I understand. You can always be up to date.
Personally, I don't see any single reason to install ubuntu again.
Many arch users often say "you must go through our annoying installation process to understand linux better!" - but that's only true if the person migrating to arch is a linux newbie.
Frankly I've been using linux for 20 years and now that I am older and a parent I have much better uses of my very limited time than going through an obnoxious chroot install and configuring some files in /etc. Antergos is great.
Yeah, setting up the environment is a hassle. Happy to help if I can.
Also, how is packaging? With Ubuntu, someone always has a PPA for everything.
What I'd like is a stable base system with cutting edge apps, but I don't know if any distro offers this.
Arch has AUR (http://aur.archlinux.org/) which has probably way more things than PPA have
However, in the one year I have been using Arch as my main distro, I had only two small breakages.
The first was a recent upgrade of openvpn, which required you to move some folder from one place to the other. however this was a known breaking change, so it was announced on the Arch-announce mailing list. :)
The second happened this weekend. I had been using the infinality-font-bundle, which provides a patched fonts set that is beautifully rendered. However it seems that the developer hadn't been keeping up with the new versions of fontconfig and the had been some new options added, and after an update gdk-bixbuf2 needed one of them to function. (which resultet in missing icons) This was fixed after 5 minutes of googleing.
So not something very dramatic.
Packaging:
The package manager is pacman and the standard repos already have a lot of software. And then there is the AUR, where everybody can upload build-scripts for stuff that is not in the official repositories. Most of the time they work great, there hasn't been any software at all that I had to download from a browser.
