Nothing beats the ps1 in terms of unique, cool, and futuristic design. It was a radical departure from anything else, while also being sleek and sexy. It sit on your tv stand or above your vcr/dvd player and didn't take up much room.
Everything about it. The Large Power and open buttons were simple (ps5 launch model, I sometimes forget which button is the disk eject and which is power)
It also looked adult focused. The n64 looked like a child's toy (although Sega Genesis and TG16 were doing this before the PlayStation. Sony brought the feel from Teenage focused to Adult, right at the time I about 19 or so when it launched).
The back of the box, had so many cool games (depending on year and model), this one pictured has Final Fantasy 7, Final Fantasy Tactics, Einhander, Saga Frontier 2, Resident Evil 2, Tomb Raider 2, Mega Man Legends, Jet moto 2, Tekken 3, Crash2, Hot Shots golf, and all the 989 sports games, when sony made more than just mlb. )
The ps1 took the prize with games (every genre , and had the most rpgs ever, It was Squaresoft golden era!)
Ps2 was bland in comparison. It was also lacking in terms of hardware compared to the competition. It did have a DVD player though, and the games were numerous.
PS3 was a great console. The design was unique but I didn't really like it until the slim came out, as the og was too big.
PS4 is too loud, although i didn't mind the og eraser design. It wasn't my favorite.
PS5 is too big and weird.
