Job: Money and bored or less but excitment?

If you were offered a job promotion but the position was just one the company had to fill for whatever reason but is had no importance and the work was dull. So dull watching paint peel would almost be better, however, you would earn 32% more than you earn now. Or would you rather be promoted to a job that had high importance, you had to work like a dog because of the work load. The job hardly has any 2 days a like so there is always something exciting or different going on, but it was only 4% more than what you now earn. Which job position would you go for or accept?
