So I installed EndeavourOS, the spiritual successor to the much-missed Antergos, last night. It uses the Calamares installer, and is just as easy to install as Manjaro. It also offers 6 DEs to choose from using the online installer, as did Antergos.
What you get is pretty close to vanilla Arch. Pamac is not installed; I didn't try yay.
However, it is vanilla Arch, with an 8-minute installation. Those who wish to get right to the taproot should certainly take a look.
I was amused by a guy on the forms who praised Endeavour for not taking "hours and hours" deleting programs he didn't want. It doesn't take that long to remove programs you don't want, and it can take (especially from the AUR) "hours and hours" to install the apps you DO want.
