Which for my first post?

I'm a big Greek mythology nerd, but also learning about demonology, so here's my question. Which of the choices should I post about first? Gods and goddesses of course, since Greek mythology I know the most about, will probably be Greek based. Demons we'll talk about different types of misconceptions and or some famous demons. Angels will be similar to the demons post mostly either famous angels and or misconceptions about them. Both demons and angels are not discussed much in Greek mythology, so I'll have to look up different mythology for those, but I'll try to put a bit of Greek into it.
