Being out gives nothing, as we have barely few apps there and now they redesign UI for different UX. In addition, you can't call jolla mature as some bugs have already history and still not fixed. No paid apps/eco system. Ubuntu not my fav company coz of my own believes, but even with that, they have ecosystem on desktop and can slowly port to mobile. Community is bigger and they even got few talented devs from here that I know of, maybe more I don't.
