Schloenhardt had a very strong theoretical foundation which is critical for students to gain a strong and rigourous understanding of concepts. He is also very humourous and approachable. He would reply to all emails very promptly when asking a question.
Andreas is very knowledgeable and really cares about his work. This makes him a great instructor, but he expects a very, very high level in terms of results. He also fancies himself as a bit of a joker, but sometimes isn't funny so much as a little mean.
Andreas is an excellent lecturer and works with a really interesting topic. He uses the Socratic Method which can be off putting but as long as you have done your readings and have some common sense the questions he asks are not difficult but just keep you on your toes. His lectures are always very engaging.
