- Vain but skilled highschooler in managerial position

- Colourful and moe
Classroom Crisis is ever so slightly more mature in its approach with believable scenarios and reasonably realistic characterisation. Amagi Brilliant Park on the other hand, is just a massive power-trip for the incredibly intelligent MC, where everyone else is more or less an accessory to his brilliance as oppose to being characters with their own reasons and motives.
Taking the above bullet points into account; go for Amagi if you want OP MC + cute and silly, go for Classroom Crisis if you like drama and plot-twists.
