I've been using Sailfish OS for quite some time, but I don't do all of my computing on the phone. There's quite a high friction for using any of the mainstream Android apps, so usually you have to find an alternative if possible.
I also use Sailfish OS - its not perfect, but useable. :) And the way Android and iOS goes to shit, its current state might already be better than them soon. ;-)
(Sailfish OS is improving over time, if a bit slowly. :) )
