It's unfortunate that I don't see what I think is the killer app of LaTeX mentioned as prominently in this thread as I'd like. LaTeX has first-class support for text substitution macros, which even pandoc doesn't seem to have. If you use macros liberally and semantically, documents requiring the same complex kinds of data or notation in multiple places can be controlled with just the one macro definition. This especially helps you maintain a single style throughout the entire document where another word processor may not have the ability to replace formatting throughout.
