I posted testimonials from people in this community that have experience with this both sevices. 2 of your links even say XBL was not down, or it was only for a couple minutes
If you look around the web it's a well known fact that PSN has had and continues to have stability issues. I forget the site right now, but there's a site that tracks the outages and its not even a fair comparison between the two services. There's even a bunch of sites writing stories wondering whether PSN will handle destiny or not. Literally every big release cripples PSN. Hell Mincraft took it down for 12 hours
PSN has gone down four times already this month.
You should be negging Sony for charging you for that trash
