To start, if you aren’t a great student then I think the decent/high average from Touro will do more for you than a poor average from YU.
In terms of the “Yeshiva” aspect of YU, although it has been improving it is still largely a colder “do it yourself” environment – which when combined with the rigorous schedule and coursework often takes a toll on the students. One Rosh Yeshiva explained it as “it is a beis medresh, not a yeshiva.” But as a Beis Medresh, it is a great makom Torah – the Roshei Yeshiva are huge and there is A LOT of serious talmud Torah and very serious messirus nefesh for Torah happening.
Academically – very challenging with many “jewish studies” requirements you wouldn’t have elsewhere (like hebrew, Jewish history, and bible). I would even venture to say the school takes these classes more seriously than most others. Ideally, these classes can teach you a great deal of necessary information and improve your understanding and appreciation of Torah; HOWEVER, all too frequently, I believe, they miss the boat and do the opposite.
