For the portables, I would say the Switch for sure, it is just so slick and clean, that color scheme is already iconic and the logo is amazing as well. (I also really like the dock)
For home console, i think the Wii U (not the gamepad). It is so smooth and well proportionate. I love the curves which makes it look less rough than the Wii.
Honorable mention to the GC which is just easy branding and iconic as well and the SNES which aged really well.
