I see!
I do, in fact, use Endeavour on my desktop as well, simply because I like snappiness and choice of Arch and similarly don't wanna bother with the pure one (and also EndeavourOS forums are more friendly in my experience). I run OpenSUSE Slowroll (an experimental Tumbleweed build, same idea as Manjaro, but actually done right) on my other laptop, so can speak from the experience on both ends.
With Slowroll (and my gf's Tumbleweed) I've only once faced the need for manual intervention, and it was simply to resolve a dependency change by choosing which package to leave - literally enter one number, and then it went on peacefully and correctly installing 1460 updates (yeah, they pushed a big Tumbleweed dump, 3.5 gigs total). On Arch and EndeavourOS, the last intervention was just recently, that's the one OP talks about, and they do happen more often and are more complicated than I'd like.
