I think it really comes down to what region you want to stay in. I am having a similar dilemma between $$ offered and various regions.
1. Can you see yourself happy in those cities/regions long term- 3 years for school and at least 3 years of practice
2. If you don't care about region AT ALL, then go by cost.
3. Go to a school you are positive that you can come out on top of your class unless there is one dream school in that mix. Graduating the top of your class will mean more than average stats at an average school. You can make the most of it anywhere you go in your choices.
I've been reading up a lot about DePaul lately because it is a school I am considering also (I LOVE Chicago even though I'm not from there)- spoke to a a few alumni who I know. It gets a tough deal from people, but I am noticing it will be what you make of it. One of the DePaul alums actually wrote my recommendation there and she went on to have an absolutely top shelf law career. It is just a school where, given its market, you really need to make sure you come out on the top of your class (like with all places). That seems to be the key for it.
What kind of law are you looking to practice?
I don't know much about your other schools and can't really say much about them.
