well there are a few, but by no means would they outrank a centralized gearbox in my book.
weight distribution - with each motor (cim) weighing about 5 lbs you might want an even weight throughout the chassis as apposed to a centralized one.
swap ability - for some reason if a motor burns instead of taking a transmission apart disabling your drive train (with a centralized tranny) you can just quick replace the single module that is broken.
Robot layout - sometimes it may be easier to mount 1 single motor and tranny then a full gearbox. The example that comes to mind for me is a planetary set where they are really compact.
I am sure there are more....the main thing to remember is that there is no "one and only solution" and it is all about evaluating your specific situation, and making the best decisions you can. Every team has their own reason for doing things, all of which are valid.
