Just the Switch. I think the Wii looked great in promotional pictures, but once I had it inside, it was...underwhelming, to say the least. It's like the PS4 vs Xbox One. In the pictures, I thought the PS4 looked nice, but it person it's a bit of an ugly duckling. The Xbox One (Both OG and S) on the other hand looked fantastic in person, and is now probably my favorite looking console to date, just due to how nicely it fits in my entertainment center. The photos just don't do it justice.
The Switch, for me, is kinda like the Xbox One. It seems uninspiring in the promo photos, but it looks really nice in person. I mostly keep it docked at my computer desk next to the monitor, and it just elevates the whole atmosphere, I swear.
