Nobody's mentioned the 2 I have:
Serkin/Budapest Qt. on (originally) Columbia - if Sony ever re-issued it, I missed it
Jando/Kodaly Qt. on Naxos - I bought this mainly to get the attached Schumann 5tet, but wound up listening a lot to the Brahms anyway. A swifter, lighter approach than the Serkin
I don't know how these stack up against others, but they were enough to convince me this is one of the greatest chamber works ever written, which says something in their favor I think.
