Oh, and it's a rolling release so my install doesn't break every 2 years with the new LTS upgrade.
Issues with new versions get immediate solutions on the forums, so breaking changes hardly impact you if you just check the front page of the forums when they do happen.
Arch has the reputation of being the hardcore distro, but really its so user friendly to manage after the initial setup (and I think they have an "easy" setup process if you don't want to manually configure everything now).
Meanwhile, on Ubuntu/Debian-based systems I can just install locally or use a third party repository for the things that need to be more up to date.
The reputation that things are always breaking just doesn't have merit anymore.
I'm using Manjaro (derived from Arch), so I can't talk for Arch itself but so far (2 years) it's been way more friendly to me than Ubuntu (which I used for 7 years before).
Its packages are generally pretty up to date, like Arch, but every update/rebuild snapshots the current system.
I find this pretty wonderful; if I am mucking around with packages or boot parameters or whatever, it’s way less scary; if I break something I simply reboot and choose an older generation.
