God Serena having 4 of 8 powers is about the same as Bloodman having a part of his curses shown. But since Bloodman's powers are the same, some fans have a good reason to hate him (Bloodman). We know God Serena roughly as good as Bloodman.

- God Serena demonstrated some of his powers and was then killed. Returned later as a Historia to have a battle with the heroes and to show off his Gale Dragon Slayer Magic before he was defeated and killed off.

- Bloodman had a normal battle with Gajeel before he was killed. Returned later as a Historia to have another battle with the heroes and got offscreened by Rogue (or maybe Makarov).

At least we know God Serena better that Jerome. God Serena used his magic twice, Jerome only once. And both's battles ended with one move.
