If you are looking for high quality audiophile approved recordings, MMT's performances are easily some of the best CD's available. As with everything else, however, his performances may or may not be your cup of tea, but I too can recommend his 5th. Zanders performances of Mahler on Telarc are also excellent recordings and include a CD in which Zander discusses the symphony.
Performance wise, if you like your Mahler a little more expressive, consider either Bernstein cycle. You can't go wrong, except with the Vienna Phil set on DG you may want to substitute out the 9th for his recording of it live with the Berlin SO recorded live in 1979, an outstanding performance I think!
