I think for me it's been...
For Microsoft: The original Xbox. There were very few games, and even fewer exclusives, that I found appealing released for it.
For Nintendo: The Wii. I didn't much care for the Wii U either, but the Wii in particular was clearly a system mainly for more casual gamers, which I am not. Despite its large volume of system exclusive releases, I revisit only the smallest handful of Wii games today.
For Sony: This is a tough one because I've actually really liked all of Sony's PlayStation home consoles. While part of me wants to penalize the PlayStation 3 for the initial few years wherein it cost $600, had almost no exclusive games, and boasted a horribly unaesthetic standard controller that didn't even have a rumble feature (which had become standard by then), at the end of the day I feel like they made up the difference from 2009-13 with a price cut, the revival of the Dual Shock controller design, and quite a lot of system-exclusive releases that included a number of my all-time favorite games (such as The Last of Us and Heavy Rain). THEREFORE, I will have to narrowly conclude that the original PlayStation is the Sony home console I like the least, if only because it has the smallest number of games that I revisit today. But that's still a lot.
