A lot of bitterness in this thread. While it does suck that online mp switched to requiring PS+, it was bound to happen. I would say psn is far closer in quality to xbl today than ever during last gen, and I think most people would agree. Presumably this is because Sony had invested in psn now that everyone who uses it is paying for it, which is pretty much what they said at e3 2013. And yeah there are people who still have problems, but overall things have gotten much better.
Furthermore, for those who buy a few games a year and pay full price for them, it sucks that you don't get the full benefits of the platform. However PS+ easily saves me more than the upfront cost each year. I don't know the exact savings per title, but $3~4 per $20+ game on sale adds up fast when there's a pretty good sale most weeks. I bought something like 8 games over the past 2-3 weeks, and I'm sure the PS+ discount saved me at least $20 (from the non-ps+ price). With almost zero effort you can get PS+ for $40/year, or ~$35 if you are patient and diligent. It pays for itself in no time.
