Moses is different from the other prophets; he was the highest level of all prophets. Moshe speaks to G-d mouth to mouth where other prophets get spoken through visions and dreams. Also Moses gets a direct message from G-d. Other prophets do not; they get unclear messages in dreams and visions that are very hard to understand. Also the other prophets had to prepare for G-d and purify themselves when they were going to receive a prophecy but Moses was always pure and always ready. Moses and G-d communicated at any time both ways. Moses could talk to G-d and get an answer immediately and G-d could talk to Moses and get an answer immediately, which was not possible with any other prophets. Also Moses was like G-ds pen because he wrote the Torah, which no other prophet did. Overall Moshe was a very special exception
