• 侃侃諤諤かんかんがくがく
  no-adjective, taru-adjective, adverb (with と)A four-character idiom for the arguing side of outspoken: heatedly insisting on what one believes in, as in political or committee debate. Less common; it describes the argument more than a generally frank personality.

• 歯に衣を着せないはにきぬをきせない
  expression, i-adjectiveAn idiom, literally 'not clothing one's teeth', for the blunt sense of outspoken: saying exactly what you think, even harsh truths, without softening or euphemism. Less common; suits criticism or candid commentary.
• 歯に衣を着せぬはにきぬをきせぬ
  expression, prenominal modifierThe same idiom as 歯に衣を着せない, with ぬ standing for ない; identical in meaning — blunt outspokenness that never dresses up the truth. Less common, like the ない form.

率直 is the common, all-purpose word for frank, candid speech; 諤々 and 侃侃諤諤 add the sense of boldly voicing or arguing one's convictions; 「歯に衣を着せない」 and 「歯に衣を着せぬ」 stress blunt, unvarnished directness.
