I just think it's pretty immature to think that there are "no restrictions" on God. There are restrictions on everything that exists. It's one thing to use our imaginations and think of a fairytale-land where He-Man can lift anything he wants. It's quite another to play that game in reality.
True - I prefer the non-perfect Hebrew god that seems to be struggling to understand humanity as much as humanity is struggling to understand him. The God that does sometimes muck about with freewill for the greater good (such as Joseph's brothers selling him into slavery), the god that engages in collective punishments (presumably everybody is partially responsible for the sins of the nation and so everybody should be punished), and even distributing them over generations or deferring them with the ever present promise of 'if the nation/tribe repents I'll stop the punishment'.
And besides - he was the kind of God that welcomed a good argument (see Moses and Job).
He was a genocidal maniac at times, but at least he was something of an anti-hero. Who wants the read about the Master of the Universe when you can have the Dark Avenger?
Erm, anyway the topic. Erm. No sorry that's all I got right now. Oh! Where did this omnibenevolent God come from anyway? I wouldn't be surprised if he was a Greek strawman that everybody just went along with. God is just and merciful - but he doesn't have to make your life comfortable. Erm, no. I'm done - I can't speak to the topic.
