Favorite: PS3
I ended up getting a PS3 about a week after launch and that was only because I knew people. I missed the preorder window that was like... maybe an hour. I worked in Seattle at the time. Every day after launch I went to about 3-4 stores daily. Before the job I had during the preorder window, I worked at an EB Games and knew a few of the managers. I remember going in to a store 6 days after launch and a 360 fanboy was telling me that every PS3 game would also be on 360 so I may as well buy a 360. Had I not known.... had I been a casual gamer, I would have taken his idiotic word as truth cause he's the one working at the game store. Luckily, I've been a gamer probably since before he was born. I laughed at him and came back the next day. I saw the same moron was there and immediately left. I was going up an escalator and a friend of mine was coming down the escalator. Came to find out he was now the manager of that store and he had a PS3 in the store he wasn't supposed to sell till Black Friday, but he would sell it too me if I wanted it. I came back down to the store and bought it with Resistance and an extra controller. The moron behind the counter tried to interject that they weren't supposed to sell it but he couldn't cut off the manager's decision. It was fantastic.
My favorite series, Uncharted, was born on the PS3. I also loved the Infamous games, RE5, Tomb Raider (2013), Mass Effect 2 and 3, and tons of others. It was an incredible generation.
Neutral: X360
I didn't bother owning one but I had a few friends that had it. It was ok but didn't really have the games I wanted to play outside of third party releases that I could also play on PS3.
Loathe: Wii
Don't get me wrong, many Nintendo specific games still had a tinge of fun in them, but I found out with this system that I ABSOLUTELY HATE motion controls. I almost instantly regretted getting rid of my Gamecube. Luckily, my Wii could play Gamecube games so that's basically what it became. Skyward Sword was the nail in the coffin for me and it ruined me on Nintendo as a whole until the Switch advertising came out stating "Play how you want" and showed the Pro controller. After the Wii-U heavily advertised continued use of the Wii-motes, the system was DOA for me.
The only game of note for me was, Xenoblade.
It is hard to say. Kinect being the vehicle that kept Microsoft financially in the console space for the last two/three years of that gen and cost them the whole of next-gen sort of rules them out, despite gaining tangible market share that gen, and held onto 20% of the gain by the end of the following gen even in spite of them failing to understand where they were at, and what power they had to bring about their negative Xbox One changes to the market.
Wii, well it truly showed that great games sell hardware, even if just a single solitary game. Love it - as it is now in Switch sports - or not, Wii Sports was more than a gimmick, and something I appreciated more last weekend after replacing all those lithium ion batteries in my move controllers and navigator and trying the tennis in (PS Move)Sports Champion - and playing a bit of KZ3 on the shapshooter.
Like Space Invaders, Lunar Lander, Pacman, Marble Madness, Super Mario Bros, Space harrier, Out Run, Afterburner, Virtua Fighter/Tekken 2, ISS Pro Evo, etc, Wii Sports brought something completely new to gaming as the best of its moment - despite the Switch version being the finished article - and on that basis, the Wii is arguably a contender. If not for the huge subsequent failure of the Wii U causing Nintendo to exit full power consoles and combine 3DS and Wii U to make a hybrid: Switch it could have been seen as the victor IMO.
The PS3 lost market share, nearly put PlayStation and Sony in the crapper, cost them ownership of prestigious New York HQ real-estate IIRC and out the gate was late meaning the simple two thread - single core - system with a Nvidia Cg programmable Hdr (10bit) GPU system Sweeney still wrongly gets meme'ed about struggled to convince early adopters with default hdmi playing ports against an Xbox 360 six thread - three core - system with unified memory in its third year - beyond its egregious stutter/tearing 12months luanch on component/DSUB15 launch without hdmi - that this was a premium system worth 3 times the price of the Xbox 360 arcade playing the same games - with the exception of true HDR Assassin Creed 1 at ~20fps on PS3 - that this was the future of gaming.
Naturally the complexity of PS3 meant lazy devs like Valve and most of the industry produced superior frame rates - even with small tearing- on the 360 at nearly 720p res, at close enough visuals, that without PlayStation's first party knocking it out of the park for 5years straight at native 720p lock 30fps/60fps or Wipeout/GT5/GT6 efforts at 1080p vertical the generation could have been completely chalked up as a lost disaster financially and creatively, and in fairness by the end of the gen with MGSV cross gen on PC/360/X1/PS3/PS4 that might have been true, but you only need look at how the first party efforts on PS3 set the narrative for PS4, and how it completely dominated at its launch and is even still used by enough gamers today to only now be losing cross-gen access to GaaS/esports games, that the PS3 like the Wii could be considered the winner even back then, and only confirmed at the winner these years on when the follow up trajectories are factually confirmed.
So, it was PS3 IMO, although I still love Switch Sports and would have traded the whole gen to preserve its invention; especially when you unlock the ability to play the best AI players Reggie/Eliza (IIRC) where blocking their smash winners by cushioned reflex shot is like deflecting a sabre hit from Vader and gaming at its very finest IMHO....maybe it was Wii
