I have more than 50 recordings of Mahler, and of the many Resurrection CDs I like Bruno Walter's 1958 New York Philharmonic recording on Sony (SM2K 64447) best, followed by Otto Klemperer's mid 60 recording with the Philharmonia on EMI. I prefer these two recordings over John Barbirolli's Resurrection with the Radio-Sinfonieorchester Stuttgart (there also is one recording with the Halle Orchestra - avoid that one!) and Bernstein's New York recording. The four mentioned recorings are all 'good Mahler' interpretations of the 'frist generation' of great Mahler interpretations.
Today, Mahler is (re-)viewed slightly different, maybe too intense/dramatic/hip for my taste. Some still are able to transmit the 'mahleresque', which is required for not being lost in his long and interwoven movements. Of the more modern recordings, Fischer (on Channel Classics) has a pretty good understanding of the Resurrection (and the best sound), but I also like Andreas Litton with the Dallas Symphony on Delos, and Yoel Levi with the Atlanta Symphony on Telarc.
