Joseph, there is truth to what you are saying. However, there is a dearth of knowledge about the Torah that came from Sephardic lands. Tell me if you heard of these “Gedolim”:
R’ Yehuda Ayash
R’ Shlomo Laniado
R’ Abdallah Somekh
R’ Baruch Toledano
R’ Shalom Sharabi
R’ Yitzchak Ben Walid
R’ Refael ben Shimon
R’ Shalom Messas
R’ Yosef Messas
R’ Moshe Pardo
R’ Yitzchak ben Walid
R’ David Cohen-Skali
R’ Yaakov Ben Tzur (Yaabetz)
etc etc etc etc etc etc
