I would say Dr. Iwai from Japanese 1Z06 and Dr. Moro from Linguistics 1A03. I just finished first year and out of all the profs I've had, they were my most favourite.
Japanese was such a fun course and Dr. Iwai makes the class fun and exciting. I was never sleepy and never miss a single class.
Dr. Moro was very helpful in terms of learning the content and gives us helpful materials to help study for midterm and final.
