Playstation 1 was just mediocre and not that great. I still remember sitting in front of the TV hoping so badly that it will load the damn CD and only a very few games I really enjoyed.
Playstation 2 was the absolute king tho, the best console at that time by far. A ton of amazing games. The graphics that the console could pull off were amazing. 10/10 for me personally the best console ever created for its current time.
Playstation 3 was the worst of all Playstations, just look at the poll, people seem to agree. :P
I think the Playstation 4 is very close to the Playstation 2 and I still use it daily - so hyped for the PS5.
