I think eternal life would be a bad thing.
As for not existing, that is what you did in the year 1800. So that is what the year 2200 will be like for you.
Epicurus put it this way:
"Accustom yourself to believing that death is nothing to us, for good and evil imply the capacity for sensation, and death is the privation of all sentience; therefore a correct understanding that death is nothing to us makes the mortality of life enjoyable, not by adding to life a limitless time, but by taking away the yearning after immortality. For life has no terrors for him who has thoroughly understood that there are no terrors for him in ceasing to live. Foolish, therefore, is the man who says that he fears death, not because it will pain when it comes, but because it pains in the prospect. Whatever causes no annoyance when it is present, causes only a groundless pain in the expectation. Death, therefore, the most awful of evils, is nothing to us, seeing that, when we are, death is not come, and, when death is come, we are not. It is nothing, then, either to the living or to the dead, for with the living it is not and the dead exist no longer."

As for the traditional Christian, he had better get it right, or instead of feeling high for eternity, he will be in hellfire for eternity, if his beliefs were correct.
