Ok, I'm a bit difficult in this regard. Because back then, I remember people drooling over the graphics of Doom. No, not 2016, they drooled over this:
I always thought the textures looked shitty and liked the graphics of Dark Forces a lot more, although it was technically barely a step-up:
Because the texture were more meaningful. With other words, technical stuff aside, the people on Dark Forces invested more time in art. And this is the main thing I see stays relevant over time. The most technical highlights of a time lose their charm as the technology advances, but the truly artistic games stay ahead. Sure, more pixels are always cool, but it isn't important in the long run.
So if asked about visuals, Okami on PS2 in my opinion beats about everything on PS3 (except Okami HD obviously), X360 and so on. So, difficult question.
