Thank you cal3713, I do remember that paper ages ago. I will point directly to the conclusion:
I believe I noted above that ABX was statistically more robust.
Our main conclusion, however, is that it is not necessary to invoke any advantage for hedonic judgments to explain our earlier results. These, and the new results here, are just particular instances of the advantage in statistical power that Ennis(1990) shows forced-choice methods to have over triangular tests. More consistent judgments are a consequence not of greater sensitivity to hedonic differences but to the statistical properties of the decision rules followed in different tasks.
