i am not familiar with the top GD schools, but remember to not only look at the top schools, but to look at the most known schools as well. I had to decide between Drexel and Penn State. although drexel is one of the top engineering schools, a big reason i went with Penn State is because everyone knows penn state. so far this has paid off big time (at career fairs and speaking with companies when i mention penn state they spout of 3 or 4 employees that were graduates from psu... it is nice for getting the foot in the door.
so make sure you look at the school's overall rating in addition to their rating for your major.
