I like the feel of it a lot, honestly. I never interact with the social features on consoles, as I mostly play single player games. Or, if I do play multiplayer games, it's with friends that I communicate with over Discord or something. I like that things are silo'd. I never found any of the social information useful on PS4, it always felt like clutter. Just get me into the game I want to play.
That said, I agree that accessing the social features is a complete pain in the ass. Trophies feel hidden. Not tucked out of the way, straight up hidden. I also literally never want to access a game's hub, so I don't understand why that option even exists, since you can just go to the main menu and press down on the d-pad to access it. But the game hub is the same thing, just....by itself? Weird choice for a hardly used feature, I'd imagine. The hub doesn't display any information, either.
I still don't think it's anywhere near as bad as the original Xbox One UI. I legitimately could not find anything I wanted on that system and I felt like there was information overload at all times.
