qfq: an important weighted queue discipline which lets you balance bandwidth within another class, so it's useful to place below a HFSC class to balance the users within the class in a purposefully weighted unfair way. it's more efficient than drr so if a choice needs to be made between the two for size reasons, qfq is preferable
drr: does similar thing to above but less computationally efficient... probably not needed if qfq can be provided
sfb: this can be a better qdisc if you are trying to do fair queueing on UDP streams which do not respond to signalling the way TCP does, this will tend to delete packets from the "heavy" streams.
Overall it's important for good custom queueing to have all of the following qdiscs in my opinion:
hfsc, red, cake, qfq, bfifo, pfifo, sfb

Supply the following if possible:
all devices
current release 19.x.x and trunk
install kmod-sched see that it does not have a full set of qdiscs which reduces the utility of targeted high-interactivity scheduling designs such as:

The most important ones in my mind are:
