First and foremost, I encourage you to focus on what your long-term career goals are, and then assess which job will best assist you to getting to that point and help you to gain additional skills and experiences that you will utilize in the future. This should be your top consideration, vs which will help you get into b-school, because that will lead you to choose the option that makes the most sense for you, and ultimately be more genuine.
To delve deeper, on the surface it sounds as though the Team Leader option would provide key leadership experiences that are important for managers and to admission to some b-schools. But I would carefully consider my paragraph above too! Good luck to you!
