One difference between fq_codel and Cake is that the former - which has no shaper - will "bypass" packets when it's empty and there's no back-pressure filling it. In that case no packet classification occurs and filters will not be called. Or at least, that's how it used to be set up; I haven't looked at it recently. Cake does not rely on the same set of assumptions, so will always call the filter.
