It's all a matter of perspective, but here's mine:
I think life is more frightening, because in truth you can only be afraid of something while you are alive. The whole concept of fear, awe or anything like that was created by living minds, even the fear of death.
On the other hand, I am an atheist and I don't believe in life after death. For me death means ceasing to exist and ceasing to exist is not scary because first of all it is nothing. You can only fear something if you exist, or in other words, you are alive.
