Well Moody's wins this contest, because it made slightly better judgements on the Aaa tranches according to this study. The other tranche downgrades need more analysis to make a judgement, ie proportion of AA, A, BBB downgraded with a more granular assessment of relative risk. In the end, they both miserably failed their mission (level the playing field between smart and unsophisticated investors) by downgrading hundreds of AAA/Aaa tranches that either were, or were close to, unbreakable.
