Sony: PS3. It's just a total mess to me
Microsoft: I'll go with the OG Xbox. Xbox never interested me as a PC gamer, but that one made Microsofts focus switch away from PC
Nintendo: The N64. Those early 3D graphics looked horrible back then and look even more horrible now. And a distinct lack of great games to play if you remove the handful of really good ones.

Nintendo: 1st. WiiU, 2nd. Wii
Sony: 1st Vita, 2nd PS3.
Microsoft: 1st Xbox One, 2nd Xbox.

WiiU is just... ugh. Gamepad was always out of battery whenever you came back to the console and it lacked games.

Wii: woefully underpowered and motion controls should be an option not the main philosophy behind a console. It lacked good third party support and some 1st party franchises took missteps on the Wii. (Paper Mario, Mario Party).

Vita: Honestly if this thing had actually sold it would have been great, unfortunately it's support disappeared after a couple of years. I like the Vita, it just didn't get the support.

PS3: It's ok, but it was a chore to use as it approached the end of it's life in my opinion. It just felt so outdated and slow, especially on the OS trying to load the trophy list, or the PlayStation Store that got slower and slower with every update. The PS4 now doesn't feel nearly as dated and terrible to use as the PS3 did in 2012.

Xbox One: The OS is really unintuitive imo, I think it's changed a few times I used it in 2018. It was really annoying to find your way around the system. The games are ok but as a console it's the weakest of the three and considering I can play all it's games on PC I have little use for it. I essentially bought one as a stopgap until I could get a new GPU and upgrade my brothers PC so we could play Forza Horizon.

Xbox: Had some problems for a first attempt. Duke controller was massive and not good to use, S controller was fine to use but the wires always seemed to come loose inside over time and intermittently disconnect when you moved them. The box itself was also massive. It had some good exclusive console titles though, like Kotor, Blinx, Quantum Redshift, Phantom Crash. It's interesting library, 4 controller ports and generally superior third party versions made it a good console.

ps3: expensive, slow and PSN in particular was awful

Wii U: Nintendo's weakest software lineup and the Gamepad was just plain old stupid

Xbox One: Just god awful exclusive lineup, very disappointing. Only console I have ever sold mid generation, and I have owned 15+ consoles

I am a bit shocked at how many are listing the Wii. I get the motion controls were strange. But between Metroid Prime Trilogy, Galaxy 1 & 2, Xenoblade, Skyward, Twilight and a few others.. I thought the Wii was pretty awesome. Very good games. Pikmin was way better with motion controls.

Really no different than both the Xbox One and the Switch. Right?! I'm also confused as to the overall bad performance. How was the vanilla PS4 performing poorly?

Nintendo: Wii U. Actually a close call between this and (please don't hurt me) the Gamecube, as both systems had an 18-month spell with tons of great games, and then absolutely nothing. However, the Gamecube was at least a well-designed system that was never going to have any prayer of competing against the juggernaut that was the PS2; by contrast, from a pure hardware design standpoint the Wii U may well be the worst console ever produced by a major manufacturer. (I won't deny that the Wii was weak for the era and had a major shovelware problem, but I just have too many fond memories of playing it with friends and family to rank it below the Wii U or GC)

Sony: PS3. Too expensive, lacked decent exclusives until near the end of its lifespan, and too many of its multi-platform releases looked and/or ran worse than their 360 counterparts. That said, my least favourite Sony gaming system overall would actually be the Vita, as there were just so many bone-headed decisions that completely squandered the system's potential.

Microsoft: Xbox OG. A solid first effort from the company, but in retrospect its library was kinda undistinguished outside of Halo 1 & 2 and a few other games, and far too many of its multiplats were just minimally-upgraded PS2 ports (though to be fair, the Gamecube had the same problem). Xbox One could have been a LOT better, but it had a few things that came along later (including back-compatibility and the Game Pass) and put it above the original.

The Store on PS4 is getting closer and closer though.

OT: I better try to be on topic for once. It's a bit tricky for me as I only buy a console when I know that it has enough quality content to not be a disappointment. But I guess I can rank the ones I've owned (from best to worst).

Sony: 1)PS3  2)PS2  3)PS4  4)PS1  5)PSVita

Nintendo: 1)GBC  2)3DS  3)GameCube  4)GBA  5)N64

Microsoft: 1)XB360  2)XB

I've basically liked every console from the current big three. But, if I have to choose, I'll go with XB 360 for hardware problems, PS3 for ridiculous price and hardware problems, and WiiU for that terrible gamepad that lagged like crazy and looked like something from the 90s.

Sony - PS3. Removed BWC and initial high price point (though that didn't affect me as I bought it when it was cheaper)
Microsoft - Xbox One. Lack of games/support
Nintendo - Wii U. Lack of games/support

Nintendo:
Wii because i don't like motion controls. Forced motion controls ruined a lot of games for me.
In second place is Gamecube because it has one of the worst classic controllers in human history.

Microsoft:
Xbox One because it has no compelling games. I just turn this gigantic brick on once a year to test a backwards compatible game for a few minutes.

Sony:
I really do like all of their home consoles so i have to go to their handhelds.
There, Vita is by far their worst device ever made. Just one account per memory card and switching cards or even accounts is a hassle because it messes up all your installed games. Pretty bad and useless rear-touchpad instead of additional buttons which made remote play pretty much unusable. And the games library consists of either crappy japanese hardcore-otaku-games or games which are played better on other systems.

Nintendo: Wii- the Wii was pretty much the home of shovelware trying to make a quick buck on a gimmick... the waggle controls were not fun and Nintendo didn’t really release any games that I really like until the end of the generation... after petitions forced their hand to release xenoblade and the last story.

Sony: ps3 - the ps3 operated as a blu ray player for a big portion of that gen. Sony didn’t start releasing any good games until the end of the gen, also, multiplats played significantly worse for the most part on ps3 even though it was the more expensive and supposedly more powerful hardware.

Microsoft: Xbox one - This gen has been terrible for Microsoft. Their first party effort has been incredibly lacking. I waited until the x came out before I bought one and... really, it has acted as more of a paper weight. I literally never have any reason to turn it on. When I do... it is usually just to play a 360 game...
