PSP, my brother had one, didnt play anything on it other than the simpsons game (which i did enjoy actually)

PS3. Lacks the quality of games and vision found on both the PS1 and PS2.

ps2 by a mile. Apart from Tekken 5, Dragonaballz Budokai 3, and Spartan, I can't think of any other games I loved on it.

For me it's vita/psp/ps3/psone/ps2

PS3.

Long updates, too many updates , slow ass browsers, too many shooters, felt like a crappy PC , no innovation aside from software like LBP and other games, Sony tried too hard to make up for its short coming that they had to rely on western developers to make games, and we got uncharted...

psp, i couldn't care less about it but i do little bit about vita and all home consoles were very interesting to me.

PSP for me, Still a great machine and had some awesome games but I have enjoyed PS1,PS2,PS3, PSvita more.        PS3>PSVITA>PS1>PS2>PSP.

By 7th gen standards I found it very "broke." It was blocky, not ergonomic enough, and too small. Thankfully the PS4 looks to be fixing it.

PS3.
Although a great media platform, it's been too dated for too long. I have not played games on it for years and dropped it for my PC a long time ago.

PS3.

Only own two Sony consoles though; the PS1 and the PS3.
It's definitely not the PS1 as that thing was part of the awesome 5th gen and is one of the best consoles ever made. So. Many. Awesome games. PS3 was good too, but it has many flaws. Also, the best PS3 games are worse than the best PS1 games. PSP never interested me in the slightest, PSV actually does, but as of now it only has one game I want to play, and another still in development. Too few for a console one-and-a-half years old.

PS1 > PS3

However, it's not all bad. 'Worse' is also too harsh a word. Sony has been my #2 for most of my gaming time and I will admit that their offering have been more consistent than my #1's offerings; Nintendo. The PS3 is better than my least favorite Nintendos, but the PS1 is worse than my favorite Nintendos. Since it's unlikely that Microsoft will sway me, Sony will again provide me with my second console in the PS4. I'll take the mediocre analogues for granted .

PSP, followed by PS3. Never played the Vita.
