The fact Sony got rid of most of PS3's critiscism (except the CELL architecture obviously) during the PS3 lifespan has a lot to do with it.
If you look at 360 and Wii last few years on the market, 360 mostly had Kinect exclusives and multiplats and Wii had some shovelware every other month, while PS3 had quite a few highly rated exclusives.
They also introduced the biggest features of the competition mid gen, namely motion gaming and a more stable PSN.
Thus when the PS4 came out, the level of satisfaction with the PS3 was higher than the one of the Wii and 360.
