If we're talking MK64, an argument for which is better can be made, but Mario Kart in general? I'm not so sure about that. The series has changed since then. Heck Double Dash and later games are almost different beasts altogether. I don't mean to say the game feels dated, but this kinda feels like if MK64 was being compared to MK8.
Wow. Are you implying MK8 is better than MK64?
