Xbox vs Playstation

Hey there, I'm a believer that Xbox simply dominates Playstation and other competing Consoles simply in its features and services alone. Mainly what I'm considering when I say this is Gamepass vs Playstation Now, it's no competition at all. And so in light
of this I had wondered, how familiar are you with Playstation's Share Play feature? Does anyone know if Xbox has thought about implementing anything similar? I think LAN parties and Couch Cooperative play are huge milestones in gaming and I think people love
that about games. So especially considering these let's say quarantined times it's the perfect time for a move like this. What do you think?

Thanks for your time.
