Having recently seen the effects a boring, hard, stressful job can take on someone, I'd pick fun job over money.
My case in point is my Mum, she's been working at the same company for nigh-on 30 years now. She manages accounts, sits behind the desk and working 12-hour days was not uncommon for her. About 2 months ago she started feeling really strange. She had absolutely no energy, no enthusiasm for anything and felt completely un-connected with everyone, even her closest family and friends. She was a completely different person. It got so bad she got signed off work for a month by the doctor, but she only got worse so now she's off work for 6 months and spending some time in the Priory. Thankfully, she is getting better, but it's going to take all of those 6 months, if not more, for her to recover fully. At which point she's going to quit that job and find something she loves doing.
This all came about because of the stress of work just building up over the years until it finally boiled over. She was in a state for a couple of weeks, and having seen first-hand the effect a job like hers can have on someone, I know now that my main priority is doing something I enjoy.
