Well said, there is not THE camera for street shooting. Some people prefer rangefinders, other P&S, others medium format, others SRS with long tele lens or ultra wide angles, my advice is take whatever camera and lens you are so comfortable to use that you can use it in the dark and put some film trough it while walking around your town. Then evaluate the results and see if you need to change something.
Besides, my favorite street camera was the Yashica T4, just replaced with a Nikon 35TI, both loaded with 400 ISO B&W film or 200 ISO slide film.
