Can't compare MK with GT or Forza, those are simulators and Mario Kart is a fun entry level karting game.
Between Forza and GT, Forza makes it easier to drive and is a great game. GT is the ultimate though, both excell in simulation tactics but GT has never held my hand through the process. I learned how to become a better racer from GT and the wealth of cars and tracks in the GT franchise is unmatched.
