This is one of the most important choices you will make after graduating from college. There are many factors that you will need to consider, including salary and benefits, location, role / responsibilities, work environment, etc. Choosing a job will depend on what's most important to you. For example, if you have student loans and other financial responsibilities, you may choose the highest paying job. Or, you may give up a larger salary to live in a city you love, closer to friends and family. I recommend making a list of your top priorities and then matching the various job offers to this list to help you determine the best fit for this stage of your life.
However, keep in mind that in today's world, 'job hopping' is much more common for young people. According to the attached Forbes article, 91% of millennials expect to stay in a job for less than three years (http://www.forbes.com/sites/jeannemeister/2012/08/14/job-hopping-is-the-new-normal-for-millennials-three-ways-to-prevent-a-human-resource-nightmare/#70b747ed5508). Moving between companies can lead to a more fulfilling career, and is even said to speed up career advancement. So whatever you decide, I wouldn't worry too much. You can always change your mind, and according to this research, changing your mind and changing jobs can benefit you in the long-run!
Hope this helps!
