I voted for Booth.
rhyme, riverripper and 3underscore have provided very good reasons. +1
I would add something more.
I think that $ makes you mulling about your decision. see my example below.
Pros and cons of schools have been discussed before and htey are fairly equal top MBA programmes.
I think that even now after long posts and discussions you are tempted by HBS mainly because of its brand. look at the heading and voting- you put HBS first, but it may be accidentally.
Personally I would not choose HBS because as you said students at HBS are younger. They tend to admit younger candidates.
Among reasons I think younger students have less expereince, knowledge and expertise. At the age of 26 they have 3-4 years of experience out of which 1 year-for "monkey-do & monkey-see" job (though there could be exceptions but generally it is so) and a 1 year for MBA preparation (GMAT, applications, and etc.) and half a year when you got an admit . So full time experience of an admitted candiated at the age of 25-26 looks like 4-2=2 years.
Of course it depends! you may meet a very bright candidate at the age of 24-25 at HBS and a mediocre one at the age of 29-30 in other schools but IMHO on the average older candidates have more experience and you learn from experience as well.
Now I will give you an example, simple and may be funny a bit: Just imagine you would be offered admits in the folling scenarios:
scenario 1: admit to HBS and Booth with no $ (was discussed before) I think you will choose HBS.
scenario 2: admit to HBS and Booth with 2 k$ what would you choose? I think HBS this time again.
scenario 3: admit to HBS and Booth with 3 k$ what would you choose? ........?
.............................................................................................................................................
scenario 100: admit to HBS and Booth with 100 k$ what would you choose?
At a certain point you will not be sure about HBS and tend to choose Booth. think about it.
just my 2 cents.
