These semantics are making my head spin. Here's my take on this:
If biblegod knows everything, but allowed a&e to fall, then he is clearly a dick.
The xian response should be, he is the Lord, and if you say he's a dick, he's gonna get your ass but good!
If biblegod does not know everything, then he's not a dick. He's just a god in the same way as other gods are gods... flawed, doing the best they can or will.
The xian response should be, words like perfection are used as logical tricks by atheists. We don't know why it happened the way that it did, but god provided an escape route, so we could be redeemed, praise jebus.
Where they make their most common mistake is to collectively use either and both answers as needed. It's either or. They are mutually exclusive.
