I don't own any special edition consoles, and don't really look to buy any. I enjoy seeing them because many of them looks quite nice, but I don't really want to see any one franchise get one in particular.
My favorites are the Mario Red and Animal Crossing Switches. The red casing on the Switch itself is really nice to see since it's the only time outside the Lites where they've done that (so far). Plus, that shade of red is fetch af. The Animal Crossing Switch has the prettiest Joycon of all, and I love the art on the dock. The full paint job those two give to the dock put the rest to shame, imo.
