It's fun and tough to have such a situation. It's great to have a forum like this to seek some guidance. Take all the thoughts and info to help look at the pros and cons. In the end you have to decide what's best for you.
That said, ask yourself these questions:
-What or where are you trying get in this crazy industry? (i.e., large cargo, fractional, airline, large corporate gig)
-Culture of each company? Flying with boring or rough personality types makes a day of flying hard to stomach.
-Do you need jet PIC time? Remember, any one can follow (SIC), but not everyone can lead (PIC). The right PIC time is still very important in some parts of this market.
-Job security better at one then the other? Jet fuel not getting any cheaper.
-Benefits package? Do you need to worry about such with a family?
-Look at the overall QOL of life issues.
I hope some of this helps as does the other answers you have received. Good luck!! In the end things have a funny way of working out. So no matter what you decide don't regret it nor look back.
