Actually, for a long time now the codel wiki has recommended using sch_fq
instead of fq_codel for servers.
It seems Ubuntu defaulting to fq_codel is a result of using systemd which
adopted it as default almost 4 years ago. There was a request to change the
default in systemd from fq_codel to sch_fq in order to support pacing but
the issue was closed when tcp internal pacing was introduced in linux 4.13:
