Not necessarily 6, but KDE Connect is such a seamless experience of integrating your phone with your computer out of the box.

Sure, there's Apple Continuity, but looks like it was released 2014 (KDE Connect - 2013) and it's tightly locked to the Apple ecosystem. And yes, the 2013 version doesn't have the same feature parity or stability as the current one, but that's ok because we're not discussing bugfixes or polish.
It's innovative enough that GSConnect is the Gnome implementation of the KDE Connect.
