Rhythmic complexity of salsa singing vs. rapping

Is it just me, or are many examples of the vocals in salsa (and maybe
Afro-Latin music generally) just as rhythmically complex and as
rapping?

Is there anyone who reads this, who is at least a sympathetic listener
when it comes to rap, who can comment?  (I don't think I can describe
myself as sympathetic to it at this point.)

There seems to be this idea among some hip-hop fans that because
hip-hop is largely rhythmic, and has only the most minimal melodic
content (not in rapping itself, but it some choruses, samples, etc.
lest anyone think I am considering rapping melodic), that it therefore
must be more rhythmically complex and engaging than other forms of
music which are more watered down, so to speak, by things like melody
and harmony.  But that doesn't necessarily follow.
