No reason, it's just the SDN conventional wisdom that more dollar signs = better.
Allow me to add some more "guy on internet" conjecture. These are the things I am concerned about long-term as a medical student:
1.)How much dedicated board study time do I get next year, and what does the 2nd-year spring semester course load look like?
2.)Will my core rotations be at hospitals that don't suck? Will there be a lot of pre- and post-graduate medical education there?
3.)Does my school have any kind of reputation or name recognition with residency program directors in the region I want to do my residency in?
4.)Am I going to have the opportunity to get letters of recommendation from residency program directors in my desired specialty prior to interview season in 4th year?
Add to that a previous question during my school selection process: Am I comfortable living near this school for a minimum of 2 years? Will I be happy there?
My advice is make your choice based on the answers to questions like that. The rest, IMO, is window dressing. Most DO schools are pretty much comparable, and the important differences depend on the applicant.
