If the cost is similar I would recommend going for fit. If you have not already visited, do so if possible and decide if you can see yourself there. They are different enough in size, location, environment, etc. that the choice should be apparent.
The one unknown seems to be Ross admission. I assume you would hear pretty soon. Ross is very large and one of the best known business schools and will probably have some recruiters there that don’t come to W&M. You would also have your admission already in hand if they accept you. At W&M you would have to apply sophomore year, which shouldn’t be prohibitive but is something to consider. While less well known, W&M’s business school is quite strong and has excellent facilities and is known for good teaching.
