Maka Wuhu
Super Mario Kart: Overall mediocre tracks that are generic as hell. None of them particularly stand out to me, and almost everything that game did was outclassed by later installments.
Mario Kart 64: Also has a lot of mediocre and lifeless tracks. It's a step above Super Mario Kart but its outclassed by its racing contemporaries of the time. Also houses the worst track in the series, Yoshi Valley.
Mario Kart Super Circuit: Has plenty of very fun and great tracks. It's the last 2D installment, but its tracks are a major upgrade from Super Mario Kart, being filled with much more life and variety than what we see. It's a shame that devs wasted the game's variety for retro tracks on the most generic tracks like the circuits and Bowser Castles though.
Mario Kart Double Dash: Mixed bag mostly. Has some great tracks, has some bad ones, a bit of mediocre ones.
(Unranked) Mario Kart Arcade GP series: I haven't played 2 and DX in a while, but I did like some of tracks they had to offer, namely Rainbow Coaster / Rainbow Downhill, the Bowser's Castle courses, Waluigi stadiums with the dinobots, Bananana Ruins, Diamond City, and the Yoshi Parks. Their tracks aesthetics look very nice and I wish we could play in them in the console releases.
Mario Kart DS: Had some pretty good tracks overall. Some of them were one of the series best even.
Mario Kart Wii: Has some very, very weak and mediocre early game tracks like the typically terrible and generic circuit tracks, but has great Star Cup and Special Cup tracks.
Mario Kart 7: Has a lot of strong tracks. I would have liked and loved all of their Star Cup tracks if Maka Wuhu wasn't there being a terrible track overall. Did we really need another Wii Sports Resort track, even? Wuhu Loop was fine enough.
Mario Kart 8: There are no tracks that I particularly hate in this one, has a lot of strong tracks. I do dislike Mario Circuit and Excitebike the most, but for the former's case I tend to dislike the circuit tracks since they tend to be utterly generic and boring.
