My data stuctures course used AOCP but we skipped the first section on MIX, and didn't use MIX at all. "Just ignore that junk," our prof said. I have fond memories of the second half of the first volume. I've used the other two volumes as references. The fourth volume I bought, but haven't had time to read in any detail; I might never get to it. Personally I liked Sedgewick's books on algorithms ("light and fluffy and readable") though I can't stand his coding style.
