Has Filip announced what TYPE of engineering he wants? Let's face it, 32 and 48 is splitting hairs when it comes to undergrad engineering degrees. At surface value, a degree from ND is going to carry more weight than CU. I love CU, and think we're a great, public university. The non-Ivy, private schools like Stanford, Duke, ND, etc. are a cut above though, particularly in terms of the students they admit.
If Filip wants to do aerospace engineering though, CU is one of the better programs around. Biochemical engineering is also strong. A lot of the other disciplines are strong as well, but not sure how they compare really nationally. If academics are critical to him, I'd be afraid of ND stealing him away. They have a lot prestige than CU, and some of it is well-earned.
