1. PS2 - The greatest of the greatest. Nostalgia is clearly talking but its library is objectively of insane quality.
Favorites : MGS2/3, Silent Hill 2/3, Fatal Frame 1/2, GT 3/4, GOW 1/2, GTA 3/Vice City/San Andreas, FF X/XII, ICO, SOTC, Tekken 4/5, Ace Combat 4/5, Gradius V, DMC 1/3, Katamari 1/2, Persona 3/4, ZOE 2, SMT Nocturne and the Digital Devil Saga games...
The number of absolute masterpieces in this machine is unmatched. Thank god the Dreamcast got killed by this incredible console and not by, I dunno, the Pippin !
2. PS1 - I'm a retro dude so a lot of PS1 games are still pretty playable to me.
Favorites : Castlevania SOTN, FF 7/9, Xenogears, Suikoden 2, Parasite Eve 1/2, Soul Reaver, GT 1/2, Oddworld, the Spyro trilogy, Ridge Racer 4, Ape Escape, Omega Boost, Silent Hill, Resident Evil 1/2/3, Tony Hawk 1/2, Tekken 2/3, Fear Effect, MGS, Wipeout 1/2097/3, Klonoa, Crash 3, Crash Team Racing...
Ahhh the memories ! Again Sony got what gamers and devs wanted a lot more right than Sega, even though I love the Saturn.
3. PS4 - The right machine at the right time. Simple architecture, easy to manufacturate, easy to develop for, not filled with DRM, and we can still buy second-hand games. And the best Dualshock yet. Not a very exciting machine specs-wise but it delivered.
Favorites : Bloodborne, Spiderman, Horizon ZD, God Of War, TLOU Remastered, Drive Club, GT Sport, The Last Guardian, SOTC Remake, UC4, Gravity Rush 2, Wipeout Omega Collection, Ratchet & Clank, Yakuza 0/6, Persona 5/Royal. Excited for Ghost Of Tsushima.
And of course PSVR being a surprising little success with great games like Astro Bot. Can't say they didn't deserve their win over Xbox One, those games are truly great.
4. PS Vita - All those Vita haters in the thread, smh. Just for Persona 4 Golden ALONE, this system is worth picking up. It's one of the greatest games I've ever played !
And with the PSP emulation, you can play every Persona entry in it, apart from 5 of course.
Favorites : Gravity Rush, P4G, P4 Dancing All Night, Killzone Mercenary, UC Golden Abyss, Steins:Gate, Virtua Tennis 4, YS Mems. Of Celceta/VIII, Wipeout 2048, Tearaway, Danganronpa V3, Muramasa...
You can download PSP games, play PS1 games on the go, and Remote Play bayybaaay ! Such a beautiful-looking, well made machine ! Shame about the Memory cards, but still worth picking up.
5. PS3 - Didn't buy it back then, I chose 360 over this one. Apart from missing Journey, GOW 3 and TLOU (and I bought the better versions on PS4 afterwards), ehh, I didn't regret it...
Still, I now bought it for cheap and it's a nice machine.
Favorites : Ninokuni, Persona 5 (looks like shit tho), GT 5/6, GOW 3, Heavy Rain, Beyond Two Souls, the Motorstorm games, Journey, Uncharted 2/3, TLOU (runs like crap but holy shit the graphics !), Wipeout HD Fury, Ridge Racer 7, MGS 4 still trapped in here for whatever reason.
Good machine but now that most of those titles are in better shape on the PS4 (apart from MGS 4, why ?), there's not a ton of reasons to pick it up.
6. PSP - like the PS3, I missed the boat and picked up the DS instead. The system just didn't do it for me at the time. It's nice for homebrew stuff and emulation, and I remember a few friends of mine playing pirated games on it. I bought it pretty recently but of course the games didn't wow me like they should've done back then. The screen is blurier than in the Vita, and the colors are less vivid. Still, it's a very impressive machine by 2004 standards.
Favorites : Wipeout Pure/Pulse, Ridge Racer 1/2, MGS Peace Walker, Lumines, Danganronpa, GTA Liberty City Stories, Motorstorm Arctic Edge, Gran Turismo, Locoroco, Patapon 1/2/3, Monster Hunter Freedom Unite, Persona 2/3, YS 7, Everybody's Golf
Very good library, but apart from Ridge Racer and Crisis Core, most of those games are on the Vita for cheap, so I would advise to pick them up here (even though they take place, and the memory cards, god dammit...).
I must admit, there's not a single Sony machine that I would call less than good. They are a pretty consistent company and they pretty much deserved their place in the sun. Pretty excited for PS5, they seem to have a pretty nice machine in the ovens.
