Recently, I've listened to most of both series. The EMI sound better. Try the Bruckner 4th the performance is superb. The first movement of the Eroica is also excellent. The Brahms series on DG are the only ones I would bother with, the fourth is particularly good. However, I don't see the mystique. Compare his Bruckner 8th to Furtwangler, Karajan or Giulini or his Beethoven the standard list of recommende performances and I think there is no contest
