@Me12345- How could you possibly say it’s the best Yeshiva given the rest of your comment. Are you even being serious? The better guys by R’ Asher are great, but the average guy in the Mir doesn’t hold a candle to an average Brisker bochur. Trust me, I learnt in one of the Brisker yeshivos, and spoke in learning many times with guys in the Mir. There is no comparison.
@Halachayid- Why would you say that over Brisk, etc.?
KBY is vaiter more modernish/harry-ish/mizrachi-ish, though it is a great place for serious guys that fit there.
