Yeah, no idea. EOS is much better in every single way.

Maybe because many website still give recommendations who newbie in arch or Linux distro
Don’t believe it ?? Try googling it

I haven’t tried endeavor is yet. In what ways is it better than Manjaro?

My experience since I began using Linux full time for my main desktop, chronologically: Manjaro, Kubuntu, Debian stable, Debian testing, endeavourOS. Started EOS a week ago and I was shocked by how well everything worked out of the box. A bunch of things I had to tweak and fix before, like messing with NVIDIA drivers among other things, just worked perfectly out of the box. I tried it on a lark after borking something on my Debian system, kinda reluctantly since I had already made a massive script for customizing my Debian based KDE installs, but in the end I didn’t even feel like I needed it because it all just worked fine without all my scripted workarounds for everything. Really impressed. I just got the plasma 6 update a couple of hours ago and it’s mostly fine, dealing with a couple of issues before deciding whether I hit that timeshift restore and wait some more
