Be welcome. We are just a few here, but often a good few.
Check past threads, because we have discussed and argued about rankings a lot of times, and some users really did write some great stuff.
First, for PhD, top 10 means absolutely amazing programs in the US, extremely competitive. Even people with perfect profiles apply to a wider range. Usually, top 30 is still very optimistic.
Second, many people use the UTD ranking as a starting point:
Search by Journal, University, Author and Article - The UTD Top 100 Business School Research Rankings
IMPORTANT: that is just a starting point. Relying too much on rankings of any kind is really a bad idea. I totally agree that applicants should think about their own way to develop a ranking, and then do it.
For example, I'm a Marketing PhD student. Yeah, you can find some rankings for Marketing PhD. But not necessarily valid for Quantitative Marketing, and absolutely not for the topic I want to research. There are top 10 schools that are bad for me, since they do not care about the topics I want to study, and there is a school ranked around 50th that has one of the most important researchers for those topics.
Your list of schools looks like a list of famous schools, not the best ones. I wouldn't be surprised to find some of the schools you mentioned being ranked 30th or 50th for PhD. And you will probably find among the top 10 some schools you never heard about.
So, applicants usually start with a list like yours, because they are the schools we always hear about. But along the way, with more information, they start to drop some "top" schools and start to include some "unknown" schools. It sounds crazy to, for example, drop schools like MIT and Yale, and select schools like University of Georgia or Ohio State, but it can be really the right thing depending on the applicant's profile.
PS - You can disregard any rankings for undergrad and MBA. They are almost completely useless for PhD, and can really get you in the wrong path.
