@rhiaro Assuming functionality was exactly the same, it's hard to imagine how decentralization could have positive impact on a per-user basis, on a purely technical level. There's a lot of overhead that's replicated that would not be on centralized systems, and a lot less efficient use of idle resources.

But of course, there's the question of what effect on the world in general (including environment) centralization and decentralization both have, and I suspect the impact of saner politics that can bloom from decentralization easily dwarfs the technical inefficiencies.
