For machine reading/writing, not much. For human reading/writing, sexprs (or Prolog terms) are much nicer as you don't need to quote everything, for example. However, (traditional) sexprs don't have defined literal map or vector/array syntax that's different from a list - for that you need an extension such as EDN format defined by Closure, but usable elsewhere.
