The neighborhoods are interesting enough to recommend the tour. But the particular guide I had (Betty) was in the top few percent of tour guides I have had around the world and in Germany. She is artsy, very knowledgable about history, art, politics, even science, and has lived in many diverse places, including the United States. Her English is beyond fluent and at the highest level of an educated native speaker. I recommend her first, for any tour, but also this particular tour with any guide.
