There were two reasons I bought a PS3 back in the day:
1) Final Fantasy XIII -- OOOOPS. Epic fail there.
2) Sony seemed to be doing a good job of atoning for their past mistakes with DRM and rootkits... The PS3 did run Linux for a while after all, and even after the OtherOS fiasco, they were overall doing better. The PS3 was a fairly open or at least "standards-based" system - standard USB peripherals, mostly standard Bluetooth profiles. Overall, I think that under Kaz Hirai, Sony has for the most part been moving far away from their old shenanigans of old. (Of interest: Sony's previous CEO rose up through their media/film divisions. Hirai rose up through the consumer electronics/computer entertainment division.)
I was quite happy with my PS3, which is why I went for the PS4 and I have no regrets. That said - if everyone I knew gamed on Xbox One and I played more multiplayer games than just Destiny, I would consider an Xbox. (I basically played no multiplayer games prior to Destiny, and have overall been lucky to find enough friends that play it on either console to find people on the same console I own.)
