I can't speak for the Co schools; but, Utah State is awsome. Such a fun school. Logan canyon is amazing if you are a climber. As for the skiing there... I drove home to SLC every weekend to hit Alta or the Bird.
word. im a ute, and an engineer. the u's engineering is better than any colorado school, unless you're going to mines. our environmental engineering program is alright, alot of my chem e friends switched to that.
i'm a biochem major at the U...one of the top schools in the nation for biochemistry. I shit you not, my advisor actually said the following: "If you graduate from a chemistry program at the U with a 3.7...you can pretty much count on going to grad school wherever you want to." that, plus utah skiing = good enough for me
i go to westminster for the most part, but i'm navy rotc at the U so i can tell you that they're both really good schools. as other people have said, the university's got very solid engineering programs. plus both the U and westminster are in a pretty cool area (sugarhouse/near downtown) and have the best skiing in the world.
