There are schools like wcu that have had recent problems with attrition and low placement rate. LMU has notoriously terrible clinical rotations.
The state schools, in particular MSU and OSU, are basically state MD schools that misspelled their credentials.
Beyond extreme outliers such as these though the other posters are correct. Nothing magical about the majority of DO schools. So for the most part just pick the cheapest one that you like. The difference in match lists you perceive are really just due to higher stat classes compared to lower stat newer schools.
Also, most people, believe it or not, aren’t just going after a high tier residency spot so we can impress premeds on the internet. Most are just going for their field of choice in a place they’d like to live. So I’d expect a school in a desirable area to match more frequently to said desirable area for example. Because of location, those programs are more competitive than average. Thus, a match list looks impressive bc 1) that program will attract higher stat applicants bc of location, an 2) bc those students want to match at those programs. Reading a match list is like tea leaves tbh.
