Differences between the Hellenic Gods and the Christian God?

I've seen that a lot of people here used to be Christian and switched faiths. What would you guys say are the main differences between The Gods and the Christian God? In terms of relationships, worship, the ways they go about things, etc. And for those who used to be Christian, what are things that made Hellenism the best fit for you? What brings you comfort? I'm very interested to hear from you guys :)
