The choice between DU and CU was a very hard one for me to make last spring. Ultimately I chose DU, and I will say that after completing my first semester (I'm a current 1L) I'm not entirely 100% happy at DU, but I think the reason is that I'm just not sure that DU is really the right fit for me personally.
I chose DU over CU for a few reasons:
1. Location: I like that DU is in the heart of Denver, close to MANY MANY oppritunities for internships, clerkships, and jobs. The alumni base that DU has in Denver is very large and I want to stay in Denver and practice when I get out of law school so DU seemed like a great choice to make for my professional goals.
2. Cost of Living: Boulder has cheaper tuition (I qualify for in-state) BUT living in Boulder is VERY expensive and the places you can find to live in Boulder compared to a similar priced place in Denver are definitely WAY worse. To get a nice apartment like I have right now in Denver up in Boulder I would be paying almost 1400.00/month (1 bed/1bath) which is more than double my current rent in Denver. All in all my choice was either live 10 minutes away from DU in a great apartment or live with a couple of roommates in boulder to be able to afford a nice place or make a 30+ minute commute into Boulder everyday from one of the suburbs outside of Boulder. Needless to say, the living situation was very compelling for me in picking DU over CU.
3. Overall Atmosphere: Boulder is very much a "college" town, lots of undergrads all over town and it seems very isolated from the rest of the metro area. DU on the other hand is in the heart of the city so you're not constantly surrounded by the "college" feel and all of the problems that can come with living in a college town.
The most important thing is to visit both and weigh all your options (both academically and financially) when it comes to choosing a law school to attend. I have been thinking about possibly trying to transfer to CU at the end of this year, but it's not because I don't feel like I'm not getting a good education at DU, the only reason I'm considering transfering is because I'm not sure that DU is the right fit for me (for personal reasons) and if I can figure out the living situation CU might actually make more financial sense for me should I be able to actually get in as a transfer.
