It's a solid choice for a lot of the reasons you mentioned. I used it for a long time before switching over to regular Arch and I still use it as a live USB to recover my Arch install or to rollback to an older BTRFS snapshot.
I will say though that it is sorta barebones enough it essentially becomes a gateway drug to regular Arch. If you're curious, you might want to check out the official archinstall installer that's bundled with the official Arch iso. It really makes it quite easy to get a working Arch install up and running.
