I agree with Oren...look at what you enjoy the most. If necessary make a list of pros & cons of each. If necessary make a list of what you want in a career and then see which one has the most in that list.
It might also be worth looking at how the market is in each field and where the jobs are...if you choose a field that has few openings you might find yourself doing something else and not being able to do the thing you were trained for (been there myself). Also if you have no desire to live in a certain location and that is where the jobs are it might be a deterent but I would still consider it because you can move there temporarily and get the experience and then later move on to where you want to be when an opening occurs.
Hard workers with good attitudes and a team spirit are the things looked at most. I recently read a human resources journal that states the thing that came up as the most important in things needed for you job was people skills...after all you will be dealing with either a client base or coworkers and if you are unable to cope with other people it can cause problems at work. It goes back to the team work aspect.
