First of all congratulations on your offers! Both programs are reputable and it must be great to know you'll be at one of those respected programs in the coming year. Both are similarly ranked, with Goizueta slightly higher but only a few ranks in most rankings. Have you visited either schools, or at least gotten in touch with current students/alum to get a feel for what each program is like?
Have you looked at the employment statistics/hiring profiles? Of course you can get a good marketing education at any good business school, but it looks like at Olin Marketing is the most commonly cited function in terms of post-MBA hires.

Finally, if you have target post-MBA jobs or companies in mind, you can always see about getting an informational interview, attending an HR session or just getting in touch with hiring managers and asking their opinion on the two programs in terms of hiring an MBA grad.
Wishing you the best on the decision and the upcoming year!
