..For who or what? Best is very subjective...For myself its pretty great. In a world in which I exist and have all my basic needs cared for. I would not ever take the chance changing it out of fear of evil tricky genie/butterfly effect like scenarios.
Best out of all possible worlds and outcomes? Of course not. I doubt such a thing even in different worlds or universes could even be achieved.
Glance into the world just as though time were gone: and everything crooked will become straight to you.
