Okay so going in order.
Student
Pro: nothing.
Con: not sure if this is a con but the screen shakes while running. this doesn't happen with any of the other characters
------------------------------------------
Bella
Pro: High body volume. Meaning she can escape easier and the pred needs more room to eat her.
Pro: can eat students.
Con: Slow move speed.
-------------------------------------------
Satie
Pro: Fast move speed.
Pro: can eat students.
Con: She makes more noise.
---------------------------------------------
Side note: Both Satie and Bella are preds so they need to eat, if hunger reaches zero, they suffer a speed decrease.

all you need to do for Bella is leave with the book in hand. You can do this in normal mode
To make it easier on yourself, you can open the door to the exit then look for the book. or if you find the book drop it near the exit

Satie, just win nightmare mode against her.
All i can say about Nightmare Satie, is get good...
