Let me say this again.
The schools with the tiers are basically equivalent in terms of reputation, how hard it is to get in, and recruiting.
In other words, if you want to do consulting, any of the following stretch schools are the same: Kellogg, Booth, Columbia, Sloan, Tuck. Pick 2-3 based on your personal preference in terms of culture and fit.
It also matters for the community - the better you fit in, the more likely you'll contribute and add to the b-school community. No one wants an empty vessel, a zombie who's just there for the reputation, recruiting and selectivity ("I am here because I was able to get in"). Why? Because if you really don't care too much or have any opinions outside of this, you will bring ABSOLUTELY NOTHING to the school or to your classmates - and no one wants that.
It's like trying to bring in a chef for a restaurant that has no taste, no opinions. "As long as it has calories and nutrients, that's all that matters."
To use an analogy, it's liking going into a convenience store:
YOU: I have $1.75 and I am thirsty. What should I buy?
CASHIER: Lots. Energy drinks, beer, malt liquor and wine are out of your budget, but with $1.75 you have a ton of choices: Coke, Pepsi, Mountain Dew, Root Beer, Dr. Pepper, Snapple, Perrier, Orangina, Vitamin Water, Evian, or a medium Slurpee (of various flavors). Tons that you could buy. It just comes down to what you want - soda, water, juice, flavored water, slushies, etc.
YOU: it doesn't matter, I can drink anything so long as it's liquid and quenches my thirst. There are pros and cons to each drink. Please help me decide.
CASHIER (if they are Chinese or Korean): Aiyah, if you no buy, no stay. [and then the cashier mumbles something insulting in their native language]
If you don't have opinions or taste - get some. It will do you good, and help you in your applications because it will allow you to make a more convincing case why the school is a great fit for you.
