It'd depend on what you're looking for. Sedgewick covers some areas better than either CLRS or Vazirani. For example, I remember relying on Sedgewick for B-Tree since neither text covered them. Sedgewick also has an entire text for Graphs, so I presume he goes into lot more detail than others can.

If you are considering coding competitions like TopCoder, you should look at Skiena's Algorithm Design Manual. It covers a lot of ground that is not covered by CLRS or the like.

But I think between Skiena, Sedgewick, CLRS, Vazirani and TAOCP, you have fundamental algorithms and data structures covered. If you are looking to go into detail on specialized topics like say AI, these texts wont help much.
