Sony's design screams of someone sitting in front of a desk with a blank piece of paper and asked to design a new shape for the console, the appearance, without thinking about function. And then once the design was born, then tried to fit the function inside it. It's size was stretched/scaled to fit the function.
The Series X was function first, form second. It's form came from a simple idea that heat travels upwards and a natural and best way for best ventilation is upwards.
Most consoles in the past are designed in the former category, the Series X IMO is the first one that is designed with its functions in mind. But most consoles for the first couple of decades didn't produce as much heat back then, consoles like SNES or PS1 didn't have massive fans, they only had heatsinks or small fans if there was one, like the one on the side of the Game Cube. If you give engineers a blank slate to design an enclosure to fit everything in, they would design it in a way to best dissipate heats in a more natural way.
I have both the PS5 and Series X. I don't mind how they both look. The Series X is a much more discrete console, especially if you put it sideways (then not taking full advance of its design), the PS5 will dominate any room it's in and screams "Look at me". The only thing I don't like about it is the gloss black personally, I hate gloss black.
