While I personally agree with your sentiment, and much prefer arch to debian for my own systems, there is one way where debian can be more stable. When projects release software with bugs I usually have to deal with those on Arch, even if someone else has already submitted the bug reports upstream and they are already being worked on. There are often periods of a couple of weeks where something is broken - usually nothing big enough to be more than a minor annoyance that I can work around. Admittedly, I could just stop doing updates when everything seems to be working, to stay in a more stable state, but debian is a bit more broadly and thoroughly tested. Although the downside is that when upstream bugs do slip through into debian, they tend to stay there longer than they do on arch. That said, most of those bugs wouldn’t get fixed as fast upstream if not for rolling distro users testing things and finding bugs before buggy releases get to non-rolling “stable” distros.
