Mario Kart 8 Deluxe is waaaay better balanced than Mario Kart 8 on Wii U. New battle mode, two items usable and no possible firehopping against professional/online opponents should be enough to get the Switch version.
Technically MK8D is by far the best of the franchise. The physics are great. Although I believe you can have more fun witch Mario Kart 64 because of better music & voices. I first played MK64 in 2010, so it's not an nostalgia effect. Overall it's just more fun, because it's NOT technically perfect.
MK7 has the best song (rainbow road). I don't like MK Wii and Double Dash. SNES version is OK.
