Perhaps the easiest way to start narrowing down your options is to consider the types of industries in which you want to do brand management -- and then on location. If you want to do CPG, Kellogg is a strong choice due to obvious reasons; Ross, Fuqua, Johnson, Carlson, Fisher, Emory also have good reach imo. If you want to do Luxury Goods, you could look at a Stern, Columbia, even an HBS. For tech, you'll have yet another group of schools to consider, etc.
For location, keep in mind that a lot of your major CPG firms are based in the Midwest / the general middle of the country. Your tech firms will largely be on the West Coast. Luxury goods is mostly in NYC. Where do you want to be immediately post-MBA? Yes, people end up "everywhere" after business school, but you'll find that every school has their major cities and their major recruiters. Check out the employment stats for each school if you haven't already done so.
