WVU (State Flagship) [$24k] VS Duke (World Class University) [$32k] [biology or biochemistry, pre-med]

While the main two schools I’m debating between are WVU and Duke, I was also accepted into these school with similar net costs (20-30k range):
Pitt
University of Michigan
Case Western
WashU

I was also WL from JHU and Vanderbilt.
I believe Duke is the top choice out of them, but is there anything I may be missing?
