So, I'm going to take a slightly different view.
Xbox 1 lost the console wars HARD, it was only viable because MS kept throwing money at it. The PS2 slaughtered it. It's not to say the Xbox was bad, but overall I would say Sony had a much greater following, and most of the Xbox games were so "westernized" they didn't really mesh with anyone outside the US.
PS3 was slated to slaughter the 360 except they royally screwed up their release with the crazy price tag and...what I would consider an upset with the Wii release. PS3's game catalog was also lacking for quite some time, however the Blu-Ray drive gave it more momentum than it should have had. I think though, that this generation saw more multi console homes than any previous generation which skews the "popularity" a bit. I would guess that many of those multi console homes, only 1 console was used to any great length. (Many say their PS3's collected dust for much of it's life). However, the only place the Xbox 360 "won" was in the US. This says alot about Sony's grasp on the world (through the love of the PS1,PS2). There wasn't really anything wrong with the PS3 except the lack of games (as compared to 360/Wii). Whether or not they were good is subjective.
I personally think the Xbox One could have cleaned the floor with Sony/Nintendo this generation had they not completely blundered E3. Even with the changes (and let's face it preorders are just that pre-orders...I don't know a history, but not everyone follows through on them) I think many were turned off the Xbox and that may not change right away. Obviously you have the people in the US who loved the 360 and will jump at the Xbox One regardless of any feature they offered, but that number is small in the world scheme of things. I think this generation will go back to more people having one or the other instead of both, but who knows, maybe people have that much money to burn to sit and collect dust.
It will be interesting to see how this plays out.
