I'm a rangefinder fan, I have 3 including a Bessa R3M. The Bessa's are compact, light, reasonably quiet (although Leica owners might dispute that * ) and the lenses are excellent. This I think makes them just the thing for street photography of all sorts.

* Bear in mind that Leica owners are generally obsessive about the noise a shutter does or doesn't make (and a few other things too!)
