The feelings I have on this are an amalgamation of reading a lot of others peoples' opinions on the web and from taking a look at how successful people are at getting into medical school coming out of various postbac programs. My main feeling is that of course it cannot hurt to go to an Ivy League program, and be able to put the name of the school on your resume and applications. However, many of the programs at those schools are also good in their own right, which is what makes them desirable.
Its so hard to compare programs because each has different things to offer. You can compare them in terms of price, the focus of their student population, location, curriculum etc. but the reality is that med schools are looking to see students achieve the best grades they can in the most difficult classes they can manage. Somewhere, there has to be a balance. Hunter definitely is a plus on the cost factor, but you'd have a hard time arguing that the classes there will be as difficult as at one of the Ivy programs.
That said, I've read of many people who are very pleased with the experience they had at Hunter and who are thrilled not to have payed top dollar. And they are getting into schools. Again, it all depends on your goals and where you are coming from.
I hope this helps. And again, it's just my opinion.
