What is wrong with you idiots? Those ARE my top 3. Monster is amazing and is the pinnacle of anime and i'm pretty sure nothing is ever going to be better or even near as good. I've watched fooly cooly millions of times and it's just amazing. Every time I watch it I pick up on something else. As for Code Geass... I actually prefer Death Note but everyone seems to hate Death Note. But Code Geass was amazing! VERY entertaining even though I hate Mecca.
As for your suggestions:
Yes Ghost in the Shell is awesome, watched it to death. I'm considering Neon Genesis Evangelion and Planetes.
