I was thinking about this lately, but I always loved the look of the PS2. I I think the black and blue color scheme works really well. And I like the two levels like the top and the bottom part of it.
Second to this, I think the Dreamcast looks really great. The angles on it make the console look so compact. The orange light on the console is placed really well too.
Rented this a few times from Blockbuster and played it at the demo that was always set up at Costco, it was a really solid system with actual potential. Blockbuster had a program back in the day where for $40 or something like that you could rent a system with 2 controllers and 2 games for 7 days. Did the same with the Sega Saturn with similar feelings, eventually ended up owning a N64 and that was not a disappointment in the end.
The ballistic hard shell cases with foam inserts Blockbuster rented out consoles in were seriously cool I wonder if any exist still
