Either Lupin or Mccgonagall

Snape

Mcgonagall, definitely. But Lupin is in second place.

McGonaggal

I feel like lupin is the cool teacher who you can open up to and who really values everyone's views and mcgonagall is the teacher everyone respects and who knows what's best for us and who's unapologetic and unforgiving. These are two different kind of amazing teachers there's no comparison.

McGonagall is a sassy Queen

And a teacher

Mad-Eye Moody (Barty Crouch Jr)
