I hope I'm not too late in giving my opinion. And just in-case if you have already made up your mind, there is absolutely no need to continue reading further.
Ross is a terrific school. I was too keen on Ross when I started my application process. But the fact is that placements at Ross is not that great. It has been deteriorating over the years. It is located in a dead city. They are not getting enough applications (But the fact is that I still got dinged and it did hurt!!)
Now coming to Kelley, it is one of the most friendly B-schools. Although, I haven't visited or met any student from Kelley, I could feel the warmth in each of my interactions with over 2 dozen students in the past 3-4 months. It is known for its top-notch faculty, great career services, and unique academic structure (academies). Kelley is top 10 marketing school. All the top firms come for hiring. Even if you want to change your career track, you can do so at Kelley, with the financial freedom you would have. Kelley is strong/decent in other areas too - finance, accounting, supply-chain, manufacturing, consulting (although, maybe not as strong as Ross, but the difference is marginal). You will be among the cream at Kelley, and that would give you an added advantage.
Go with KELLEY!!!
PS: I too will be matriculating at Kelley with the same offer as yours
