This is not very convincing.  Do you actually know how WFQ
works?  If so, please tell us.  The doc you sent did not describe how
it works but what the effects are, and those are entirely consistent
with what SFQ does. 
High bandwidth flows are limited, low bandwidth flows get lower
latency.  Can you describe some effect that's different?
