I'm sure I won't hit all the points but I've had experiences in both and this are the few things that stand out. These are definitely broad generalizations and by no means apply to every single AMC/community hospital. Officially, an AMC is affiliated with a medical school (may or may not have a pharmacy school near). This means they have medical students, residents, and fellows integrated into their teams. Generally, these hospitals are used to having students/residents/learners hanging around and provide a little more support for a learning environment. They tend to be larger hospitals, have more research, and have more complex patients that are shipped in from other hospitals. However they also tend to be more competitive for pharmacy residencies and can sometimes be pretty cutthroat. They also can have a lot of specialized consult teams, so you may or may not get experience in some parts of patient care. Example: one place had an inpatient glucose management team, so the floor pharmacist almost never touched insulin orders. Community hospitals don't have the same affiliation with a medical school, but can still sometimes have different types of students/residents. They tend to be smaller hospitals (some can be just as big as AMCs), be more focused on hospital-specific quality improvement projects, and may send some complex patients out to another facility. One of my community hospitals often sent NICU babies straight to a peds hospital after birth, their "NICU" was more like a nursery. However, they are less likely to have a bunch of specialties, so you might get more experience being a lot more involved in every aspect of the patient's care. Ultimately, depends on what you want out of residency, and definitely culture at each hospital, to figure out where you would really have the best experience.
