The S is fast schottky logic and will pull more current per chip than LS or TTL and will probably be slightly faster (I think without getting the spec sheets out)  LS draws less current than standard TTL but is as fast or in some cases slightly faster. The functionality is of cource exactly the same. LS will probably replace any standard TTL logic though it depends on the quality of the design to be sure that you dont get timing or race problems.
