Oh, I wasn't aware that Manjaro had stable repos as well. That seems to be the main difference to arch in terms of packaging. I'm not convinced it'll save you your dependency troubles entirely, since the packages and how they depend on each other is a clone of arch I think, but if they don't update as often at least you won't have to tackle that quite as often.
I was under the impression that Manjaro is just Arch with an installer. Seems it's more that that, at least these days.
That's Antergos, Manjaro has stable (default), testing and unstable repos.
There's not dependency troubles on stable since they are reported and fixed before on the other two.
And about Linux distros, most are dead because they were personal ones or changed name overtime, but when it comes to the desktop, only a few are worth it.
But there a lot of specialized distros that make sense, like Raspbian, SteamOS, KXStudio, Super Zaxxon, etc.
Btw, Manjaro is number one on distrowatch, not that is matters much, but funny,
