OP - ''PS3 received one crap 3rd party port after another, most of which ran better on their competitor's console, leading a lot of people to believe the 360 was the better choice to play 3rd party games. Nintendo faced similar issues with 3rd parties where they got lesser ports in the beginning and eventually those dried up as well."
The PS3's 3rd party games improved, almost to the point of parity, and a handful even ran better on the PS3. Also as the wording of your post seems to imply, (even though I doubt you meant it that way), the PS3's 3rd party games support was always, always superior to the Wii-U, and never "dried up" either. So yeah, 3rd party support is one reason. Perhaps the biggest one.
