The best argument for the existence of God is biting the bullet on the dogmatic-axiomatic horn of the Münchhausen trilemma as opposed to one of the other two horns. The worst is the ontological argument, but it's also the funniest.

Good point. Thanks, PSOL.
The best argument is deciding you'd rather have your worldview be based on unprovable premises than on circular thinking or infinite regress (the only three real options). The worst argument is "God is good, and it's better to exist than not to exist, therefore He must exist, otherwise He isn't God and whatever exists instead of Him
is God," but it's also the funniest.
