Two versions I would recommend are:

Leonard Bernstein, Vienna Philharmonic, DGG 415 570-2 Complete Symphonies
plus Academic Festival Overture, Variations on a Theme of Haydn and the
Tragic Overture.  Performances done in the grand manner; spacious tempi,
to say the least.  Outstanding orchestral playing.  Live performances.

Otto Klemperer, Philharmonia Orchestra, EMI CDM 7 69651 2, CDM 7 69650 2,
CDM 7 69649 2

Complete Symphonies plus Alto Rhapsody w/Christa Ludwig, Tragic Overture,
Academic Festival Overture

Performances done in the grand Klemperer manner.  Broad tempi,
outstanding orchestral playing, spacious Brahmsian playing.  Outstanding.
