"Please note, I was looking for a relatively cheap bike that would get me around campus, nothing too special"

All three bikes fit the bill. Assuming all 3 are in similar running condition, the cheapest one ($150 univega) would be the most practicle for a campus bike.
Relative performance differences don't really play into it until he needs an off-campus bike. Arguing with and insulting forum members over a non-issue is a waste of forum space, imo.
