Netflix:
-The desatrous life of Saiki K (no joke, funniest anime with a lot of coffee pudding, lol)
-Food Wars (Not so secret, but absolutely worth seeing; FOOD)
-Magi (currently one of my favorites; really cute and great characters, great storyline and great soundtrack)
Crunchyroll:
-Bungo Stray Dogs (just has something, such a great drawing style and story / characters are great too! Somehow has its own style, really likes it)
And while it's neither Crunchyroll nor Netflix, but:
-Cells at Work (Available legally and free of charge on Wakanim, it's great! I've learned more about cells than in a year bio and it's also really good fun. Just take a look and enjoy)
