It's a very good question. To answer honestly I would say take the job with the hedge fund. You will make a lot more money and you could probably afford to fly privately if you really wanted to which is a lot more fun and enjoyable.
I never thought I would ever be saying this to anyone, considering I have been very lucky in aviation and do enjoy the job generally. What worries me is where it's all heading. The industry isn't getting better, it's getting a lot worse as the years go by. Where will it all end up? And keep in mind that I work for a UK Major out of LHR on long haul where we see fairly good T's & C's in comparison to a lot of other carriers around.
The daily abuse and lack of respect from airport security, the stupid hours we work, anti-social rosters, constant battling with the company over Pay, Pensions, roster agreements, the list just goes on. Make some good money and enjoy a nice life. I don't think the pay and conditions vs all the hassle in the job makes it worth it anymore.
It's only my opinion and I am sure you will get many others, but the very best of luck with whatever you decide to do.
Cheers
