Honestly, I wasn't paying attention to gaming stuff around the time the XSX was revealed and at first glance I thought it was just a new Xbox One like the One S and One X, meant to be more like a PC hence the tower form factor. Boy, was I wrong. It's not impressive but it's doesn't suck, it's inoffensive, it's just a box with a mesh grille on top. I think it's a weird form factor for a console but I don't have any strong feelings towards it.
The PS5... On one hand the curves, white and black colors, and lights give it a futuristic vibe. Kind of like they took the silhouette of the fat PS3 and carved the PS5 out of it. But on the other hand it's a noticeable departure from anything Sony has released before and I'm not sure where I sit on that just yet.
At this point I like the PS5 better because there's actual design choices going on.
