In addition, Jedi also have superhuman reflexes and speed. They can attack and react lot faster then a normal human can. In comparison, Wizards are like normal humans or humans equipped with magic wands.
Furthermore, Jedi's greatest asset is the Force. Jedi can use the Force to perform amazing feats and this grants them advantage in many scenarios. Jedi learn not just offensive applications of the Force but also defensive applications of the Force. Highly trained Jedi are capable of absorbing pure energies with their bodies.

Highly trained Jedi can conjure protective shields so powerful which can make them virtually invincible until the shields are given up. Jedi have lot of offensive options with the Force. They can ragdoll and even kill with telekinetic abilities. They can hurl objects towards opponents to hurt/crush them. Highly trained Jedi can form even twisters with the Force. Jedi can even paralyze individuals with the Force. And Jedi can also easily disarm opponents with the Force; they can pull weapons of opponents out of their hands and grab them themselves.
