I would not be so sure about that. The depictions of hell that I have read about are not pleasant at all.
It is enough to make one a believer even if they don't like God.

Heaven and Hell
The Afterlife Revealed
I don't know why you think that heaven would be more boring than hell. I believe it is quite the opposite.
Hell will be really boring since it consists of souls who are attached to the physical pleasures that they can no longer engage in since there is nothing physical in the afterlife. So there is nothing to do in hell except think about what you used to do on earth.
Like attracts like, but I'm not so sure you would like the souls in hell since you seem to be a nice person and there are no nice souls in hell.
Sorry, there is no way to secure termination. Blaspheming against the Holy Spirirt will get you to hell, but you will still exist, and it will be a hellish existence.
