I'm going to agree on the geographic sentiment.
Realistically, outside of the top 7(10?) schools, there is a lot of regional focus associated with the schools.
Go to Georgetown if you want to end up on the East Coast. First, for recruiting (local), second, the alumni network will be more concentrated on the East Coast and will be more of an asset there, and less so if you move away from the area.
For McCombs, replace "Georgetown" and "East Coast" with "McCombs"/"Southwest" in the sentence above.
For example, I applied to Texas and am planning on matriculating there because I want to stay in Texas. I know someone else who received acceptances to both Duke and McCombs, but ended up at McCombs because of the strength in Texas.
I used to live in Northern Virginia/DC, and when I was there (this is a few years ago) Georgetown was an up-and-comer and had some pretty good clout in the area. I'd imagine this is even more so today.
If you go to a school out of the area, you'll be recruiting against tons of people from local schools. Not such a big deal if you are a H/S/W etc. level school. More so when you move down the list to where Georgetown/McCombs/Tepper, et. al. sit.
Now if you have no idea where you want to end up, I'd lean towards McCombs, but if one is substantially cheaper than the other, that might swing the needle for me.
