I don't think you can go wrong with either job choice, but keep in mind, no matter what job you choose, you can always get another one. I think the decision will come down to what you value more. Just from what you have written, below is a minor analysis.
Job one:
Offers more stability
higher cash flow
Co-workers you know/get along with
Close to family and friends?
Job two:
Offers More travel
Very Prestigious place to work
Keep in mind, that this will probably not be the last job you ever get. Stability may not be important to you if your young, have familial support, and want to travel. Prestigious jobs do not always offer the best quality of life, but they can open doors. Depending on benefits, you can always travel for vacation. I personally have never had any trouble leaving my home town, but if that is something that worries you, take it into consideration.
Me personally? I would take job one, because being close to family is more important than travelling to me, but you seem to be very interesting in travelling and leaning towards job two, which could work out very well for you. I would do with the job that has the most important attributes to you, because if your priorities change, you can always get another job.
Good luck and congratulations.
