lol no offense to the op, but this feels like a dumb thread. Assuming what is meant by "best" is reputation (like saying Harvard, UCSF, etc.), there is no such thing for almost every MD and DO school. Do we expect that the public or most people know that the medical program at UC-San Diego is better than University of Maryland or University of Texas-Southwestern or vice-versa?
3 in 4 people don't even go to college, so they don't know jack ****. From the 1 in 4 that go to college, most of them probably don't know how medical schools rank the same way I bet almost nobody here can rank pharmacy programs or dental programs. If someone said UCSF for those, I'd probably think they went to a good program, but do I have any knowledge whatsoever if the program at University of Michigan is better? Hell, I don't even know if they have a pharmacy or dental program.
When choosing a school, choose one that fits your needs and desires best. For me, it would be a school that's affordable and in my home state. My next concern is my ability to land a residency in my home state. I seriously wouldn't lose sleep over "should I go to NYCOM or PCOM?" in a "prestige" battle
