It's really unlikely that you'll find information that will be truly revealing. And while your clinical training starts in medical school, truthfully residency and fellowship are 99.8% responsible for the type of physician you'll be as an attending. I barely remember a single thing in terms of medical knowledge from my med school clerkships now. There's a reason why intern year is daunting - you have to go from knowing only the absolute bare minimum to reasonable degree of expertise pretty rapidly.
What schools are you considering if my first question, some of us who are attendings on SDN may be able to provide an idea of reputation for residency/fellowship training, but that's still not answering your question.
The problem I foresee, even if you got great information, is how are you actually going to compare these people's experiences and reach a meaningful outcome for you? Unless you know at this very instant that you are going to be a psychiatrist or a pediatric orthopedic surgeon or an oncologist specializing in Non-Hodgkins Lymphoma or a reproductive endocrinologist with absolutely no possible way you'll deviate from that plan, how will you interpret someone telling you "well everyone loves our IM clerkship but hates peds, because in IM we have really useful daily lectures, but peds is haphazard and the residents are typically worthless which is probably why they don't fill in the match every year" when another one tells you "IM is the worst at our school, the residents have no interest in teaching and they're overworked, but in peds it's well thought out, it's geared towards our shelf and the residents recognize not everyone will be a pediatrician so they really try to find cases that will appeal to what you want to do", or "pretty standard stuff, nothing really stands out, surgery is totally reasonable and a good experience unless you get placed on the Red Team, then it's absolute hell, just stay away from being put on the Red Team unless you want to be a surgeon, and even then you don't want that team". If you know what you want to do, then it *might* make sense to go to a place with a strong clerkship, but if you don't know where your career will take you, how do you actually prioritize any of the information you're likely to get?
(descriptions of clerkships above are accurate representations of 3 different medical schools I'm very familiar with, BTW)
As someone who is now out in the attending side of things, my recommendation would be to go to the most reasonably priced school you can. If they're all within about $20k in terms of tuition, then go to the highest ranked school.
