That's some pretty weak spin talk. In the last couple years before the new consoles came out my 360 was only used for Gears and Halo. Everything else was played on the PS3. To be fair, there were some circumstances that caused that besides me just liking my PS3 better. I got my 360 on launch day and played the crap out of it. It was repaired/replaced 3 times for RROD so I likely didn't still have the same launch day system when I retired it but it was the same model.
It sounded like a jet taking off, the disc drive was starting to fail, and the tiny hard drive was only big enough for me to fit 1 full sized game on it. I got into PS3 after the slim model came out and there was no comparison. It was quiet, had a big hard drive, and I didn't have to worry about it dying. If it would have went the other way around with me having a launch fatty PS3 and one of the 360 Slim models the 360 probably would have been the one getting all the love the last few years.
His comment that people were more satisfied with their 360's is weird to me. They were comparable machines but the PS3 came storming back to take the lead in consoles sold at the end even with Xbox trouncing them for the first several years. Why was the PS3 outselling the 360 by such a wide margin for the last several years if the 360 was so much better? I don't see either one of those consoles as inherently more satisfying than the other.
The real reasons they aren't selling as well are because of price and the fact that they made the hardcore gamers who are more likely to be early adopters hate them with all their announcement gaffs. All the bad PR takes a while to recover from once you turn everyone to your competition. Luckily for them they have started to fix those problems. The press has gotten more and more favorable ever since they started listening to people. Phil Spencer seems to have them headed in the right direction since he took over. I can easily see them dominating the US market again by the end of this console cycle if they keep this up. Yes they are still pretty far behind but PS4 has only sold 7 million units so far. By the end of the last gen each console had sold over 80 million. Everything that has happened so far is still just a drop in the bucket when you look at the big picture.
