“As far as learning goes, I stand by my statement of Stein’s is a higher level of learning. R. N’ Stein is a very big Talmud Chachum.”
Health- Just because someone is a big talmud chacham, doesnt mean his yeshiva is on a high level. From what I hear R’ Gellerman is also a big talmid chacham who wrote many seforim.
