What would be the best choice? (assume that major is same for all four)
Which major?

You are junior, so your question should be which places are worth applying to.
Since you are an international applicant, you need to find out if the employers in your country care where you study. If they do, you need to target those universities.
Please remember that even if your family can cover the full cost of your education here, what would be a match for a US applicant will be a reach for an international applicant. So you if you are determined to study in the US, you will need to consider places that would be safeties for a US applicant with your profile.
Apply broadly. U Wisconsin would be my favorite among all four but it’s also very hard to get into.
UIUC has the highest ranked undergrad business program out of these and places the best in Chicago if this is where you want to end up. Illinois and Wisconsin also has the most recognition internationally/Asia if this is important to you.
Edit: Illinois, Wisconsin and Ohio State are actually tied in the latest rankings at #15.
