Hopefully, everyone is learning in the best yeshiva, that suits their own needs.
Chofetz Chaim may be great for me, and terrible for you while Ponovezh is great for you and terrible for me. The derech halimud, hashkafas hachaim, the way the rabbeim interact with the talmidim (if at all). Are you self motivated, or do you need a rebbe on top of you all day?
