Omniscience would be boring, knowing everything? Where would the fun be in life? You might enjoy it for a few years, maybe even a few decades, but it would get old. Omnipotence, the power to do anything, but having to first figure out what it is that you need to do to accomplish something? That would be fantastic. For example, say I wanted to make gold from the air, I would need to figure out what I would have to add to the various molecules in the air in order to get gold, or if I wanted to make myself Immortal I could either hold the basic structure and substance of my body constant, or I could attempt to discover the cause and solution to aging. And with omnipotence one could still make mistakes, actions you take could have unintended consequences, there is still a randomness to everything.
