Its not bad honestly but they rely on so many Playstation fixed apps to get users more entrenched in their ecosystem (which really isn't theirs) so if you want to watch Amazon Prime or Netflix or Hulu, etc you've got them as part of an application setup process. As far as game networks go though? Microsoft has the upper hand. Sony's network is so piss poor I think its always going to be second-best to Microsoft's unless someone decides to revamp it and Sony Japan just does not seem to care about that part of their market.
Nintendo on the other hand are absolutely horrible. Frequent drops, poor region management, game downloads on a 300Mbps network at 50Kbps? I know they are fairly new to this arena but surely the engineers they hired to get this working right could have done better.
