talmud -“You could find shiurim there at any level, right up to par of the best yeshivos.”
Name one Rebbe who gives such a Shiur. I’m not knocking DC, but yes there are Shiurim on levels with a lot of other Yeshivos, but not on the level of the best Yeshivos. I’m considering the best Yeshivos like Brisk, Passaic, etc. I don’t think you have a clue what Shiurim in the best Yeshivos are like – so you exaggerated.
