lul: I would not describe MMY as chardal at all. Chardal is an Israeli term and phenomenon which is basically incompatible with the American term MO. I asked friends who went to both schools what the difference was and they described MMY as more academic and Shaalvim as warmer. There are some more RW teachers at MMY, like R Teller, but the vast majority are similar in hashkafa to Shaalvim’s. I haven’t really heard from anyone of a practical difference in the hashkafa taught at each places, though I think that on average, MMY’s student body is more RW.
The other sems you recommended are MUCH more BY than any of the sems she mentioned (besides Meohr, which is probably only a bit farther to the right than DB, and maybe Pninin/Neimos).
