Well, it's totally a rip-off, but I think it's a much better game. I haven't bothered with the handheld iterations of Mario Kart, but Mario Kart Wii was an absolutely mediocre game and a bad "racing game". There's little-to-no skill involved, because of the items. The items dominate that game and I think render it little more than a party game. This game has a bit more reliant on skill and the player's familiarity with the vehicle they choose.
