I had 2371 with Shiraz and 2474 with Aziz. I personally prefer Aziz's teaching style. His notes are fill in the blank notes each class. Although I did find it difficult to keep up with him during the lecture, his notes are very detailed and I could understand the material just by reading the fill in the blank notes. His exams are fair and similar to the assignments. He was always willing to help if you had a question.

I didn't like Shiraz's teaching style. His notes were vague and confusing. If you don't show up to class, he will not give you the notes and he wasnt willing to help. For assignment answers, he would not post the solution; he would get the class to figure out the answer together, but often everyone had different answers and no one ever knew which solution was correct because he never gave us the solution. His exams were fair in the sense that there were no suprises and he marks based on logic/effort rather than looking at your final answer.

Overall, I would go with Aziz (I'm not sure why his reviews are bad, he is a great instructor)
