A question for Calvinists....?

I'm not here to pick a fight. I'm praying to know truth. How do you answer this question: Which God is greater (of course there is only one God, but indulge me); One who is sovereignly in control of everything, even the decisions of men, or One who is sovereign yet powerful enough to create beings who can freely choose to reject His love...because He sovereignly desires it that way?
