Really now, why didn't you list many more things that both services have, but only in the PS+ section? :)
Let's see:
-Discounts for games happen regularly on Xbox Live with additional benefits for Gold subscribers.
-Xbox Live
Silver also supports cloud storage for games. Suck that, PS+. :p
-Xbox Live Silver on One will also have automatic updates. Suck that again. :p
-That early access to content doesn't mean anything, a developer can freely make content accessible to Gold subscribers right now on Xbox Live, and don't allow that content to Silver ones for as long as they want.
-$60 per year for your household, the subscription can be shared with family. :p
No point in listing features on one side just because that company mentioned them during their presentation, when the other company already offers or will offer the same features.
Except the requirement of Gold to be able to access other services like Netflix and stuff, PS+ has nothing that Gold doesn't have.
Thus, they are the same, with that exception... now, I could also mention integration with Windows Phone and Windows 8 devices, being able to play the game on all these devices and share the saved games, use these devices and whatever to compliment the One by only having a Silver subscription... But whatever, they are the same. :)
