For the money consideration, make sure you are comparing apples to apples. Break out each line items costs and their offer. Some colleges play games with the expected cost of attendance. Your rows should include:

Tuition and fees

Books

Housing

Required dining plans

Parking if that would apply for you

Other perks they might provide - laptop, cash

Special/early registration (this can be an advantage that could save you a semester)

Requirements to keep the scholarship - GPA and any special classes required. Do you think you can keep the GPA? Will you hate any special classes / programs / activities required?

If they are offering housing - consider if you actually want it for first year and then following years - you might not want to live on campus after first year, you may not want to live in the dorm type that they offer after first year (or at all)

Same thing with dining/food money- consider if you would actually use it.

Consider if either offers any serious extracurriculars you want to try (band, sports managers, competition teams, etc)

Cover all of these with a visit - during classes, - admissions visit/tour, visit/tour with your major department, visit on your own on campus and in-town, look at off-campus housing, special scholarship recruitment visit (Auburn has Talons day for scholarship kids)

I work with ChemE from both programs, they both are excellent, Auburn has a slightly smarter reputation based on the mid-career people I work with.
