Daas Torah is what your Rav says about halacha. What any other Rav says is at best an interesting alternative opinion.
P.S. In all fairness, the diversity of opinions is greatly exaggerated. We look for differences that in many cases aren’t really all that significant. If you asked a secular (Reform) Jews, he’ll tell you that all Orthodox rabbis agree on almost everything – they have trouble telling the difference between a Hasid and a Misnagdid, a Hareidi and a Religious Zionist, or an Ashkenazi from a Taimani.
