I don't think philosophers should even be in the running for this title. They write way too many words when few do trick.

but talking is part of the contest (I should not have said it was about "text"; nonetheless academia still maintains an oral tradition in teaching and thesis defenses)

so while written philosophy is verbose, philosophers talking can "transfer" a lot of "meaning" with short sentence

whereas mathematicians will likely need to talk for a very long time for what they can write down in a short terse equation

Who do the few words trick? Why do the philosophers wait for that before writing their many words?

Classical musicians. Lots of information with very few symbols nevermind text.
