Hi Erik, I used to think the De Waart cycle was among the most consistent cycles. Gorgeous sound, handsomely played, hardly any audience noise. I even like his renditions of the Ninth and Sixth, which are often mentioned as the weak links. Great ending to M8, sympathetic M7, great horns in M5.
Stenz, indeed, has one of the most consistent cycles of recent years, but maybe I'm alone in not being too enthousiastic about the sound of his orchestra. Adam Fischer is a clear winner, his orchestra sounds better than Stenz's, and I even think the recorded sound is better.
But, as you said, the Berlin recordings are thrilling. I too havent heard a dismal performance in the set. Haitink's maybe a tad too slow, but so was Bernstein's in Amsterdam, and many people nevertheless like that recording very much. Objectively speaking, the BPO set is well worth the outlay!
