It is amazing how things change and develop on this career over time, just go with the one that offers you a job and in the case you do get an offer from both just go with the life style that suits you best and hope your crystal ball works a lot better than average. Just picture yourself with 7 year seniority at Eastern in the mid 80's, there is no way in hell that you would have touched any of this two outfits with a ten foot pole. Ironic isn't it?
Good luck with your decision and only time will tell if you made the right choice
