Can't go wrong with Code Geass, it has the same sort of clever that Death Note has, that said, watched the anime to Death Note recently, I actually think the Live Action movies were cleverer than the anime (and thus that possibly means the manga)!
As for Cyborg 009 vs. Devilman, it was certainly better than 009 Re: Cyborg; just some of the stuff about that movie was weird, and by going for realistic character designs, they lost their charm !
