That was kinda my experience as well when I ran vanilla Arch for a bit, First day was just finding and installing stuff that already came on Endeavour.
After I had an SSD issue had to switch to another drive I didn’t really see grabbing regular Arch again as worth the extra hassle.
I actually noticed something similar the other day when looking for Red Dead Redemption PS3 on Vimm’s I got given.
