Overall, I probably think the PS3 super slim looks the worst. I did not like the cheap sliding disc cover at all. I know they were cutting cost for the super slim but it just felt too cheap.
The PS5 doesn't look great at all, especially when placing it horizontally and the disc drive version. Definitely near the very bottom in my books. However the discless version standing vertically looks quite decent.
I saw what Sony tried to do with the PS5's design this gen and it technically worked. They wanted to make sure it stood out that no matter what you, or a friend that comes by your house and look at your entertainment center, they'll notice the PS5 because of its "unique" design. Nobody would ever mistaken it for a bland wifi modem or a subwoofer or anything of that nature. I suppose Sony also wanted to choose the color white this gen and change it up since the past 3 gens their consoles were black.
