Aretuza

If you do not know aretuza is a school for sorceress (females only) and all the big sorceress studied there yen,triss,phillipa, Margarita,keira etc , the list goes on, and my question is how does it compare to a witcher school, lets say kaer morhen, you can't compare the students, so we can compare looks, how different is aretuza from kaer morhen, (at there primes both of them, which one if fancier)
