Penn State vs Purdue?

I am an international student. Got into the molecular biology program at both. (Might even change my major later) Having a lot of trouble deciding which offer to accept. Please help?

Purdue molecular biology program is ranked better:

Whichever is cheaper. Both are good schools.
