From a “rating” or “reputation” standpoint, it’s a wash. Their ratings flip-flop based on the source and are close enough that differences are meaningless.
So it comes down to finances and fit. Unfortunately, if you weren’t able to visit the campuses, this can be quite difficult. Getting a feel for a place is tough from brochures and web sites.
I can say that my daughter will be graduating as a MechE in a few weeks, has had a great four years, and accepted a full-time job in November. But I’m sure UIUC has many satisfied students as well.
With all else being equal, it’s hard to turn down a $10k (per year, so $40k total?) savings.
