Best Mario Circuit?

I like Mario Kart 7's Mario Circuit alot but I was just wondering what people thought is the best Mario Circuit. If you're forgetting some, here's a list down below:

SNES Mario Circuit 1, 2, and 3. THE FLAT ONES
N64 doesn't have one ;-;
GBA Mario Circuit is the one that is only memorable because of the MK8DX remake
GCN Mario Circuit has the goombas and a chain chomp
Mario Kart DS has the harsh U turns
Wii Mario Circuit ALSO has goombas and chain chomps but this time it's in a figure 8
Mario kart 7 has you go into the castle and through a big pipe
Mario Kart 8 is a figure 8 but you can drive on it upside down.
Mario Kart World's is just a remake of the first 3 -_-

TECHNICALLY, N64 does have one, they just named them raceway tracks


gotta go with DS

(also you're kinda spamming topics)

DS is the best imo
