I bought this Ring highlights set on an impulse (as I already own the complete 14 CD Solti/VPO set by Decca), as Karajan is my favourite conductor. The quality of the music in the Karajan/BPO version far surpasses the Solti/VPO set (It is far richer, more detailed and has more depth). However, the main failing of this version has to be the soloists. For me, the Solti version is better in this respect as Hans Hotter is the definitive Wotan and Birgit Nilsson is superb as Brunnhilde. Nevertheless, I think the Karajan version is better overall, and I recommend it.
