I am impressed with the degree of foolishness exposed in the OP. What energizes the audacity to determine the quality of a yeshiva? For one talmid, the so-called “best” yeshiva would be a disaster. For another talmid, the “worst” could be producing a Gadol Hador. Is the number of boys that enter Brisk the yardstick?
It’s one thing to explore the characteristics of a yeshiva. It’s another thing to rate them. That smacks of holier than thou, and this is not consistent with Torah value.
