1. Not many differences.
Although they are different cities at different coasts with different styles, you are in fact in a controlled environment created by EF.
For example, Evergreen State College, where the EF campus is located (a partnership of the community college with EF), is located in the middle of nowhere. EF's Boston campus, although located next to Boston College, is difficult to reach public transportation (12 minutes of walk).
Since you are in a controlled environment created by EF, you will experience a controlled America life created by EF.
2. They are the same.
3. Then you can't choose EF. EF is a comfort zone.
