It all rather depends on what you mean by "finest recorded". Do you mean (a) best performance captured in a recording, or (b) the performance most liked by audiophiles? As you're going for one of Walter Legge's least successful productions, I'm guessing (a).
In which case, I'd urge you to try to hear Ferenc Fricsay's 1954 MONO account, recorded with the Berlin RIAS Symphony Orchestra and Choir, and a decent well-integrated quartet of soloists, in Berlin's Jesus Christus Church. Not the last word in high fidelity, but the performance packs a hell of a punch! Available on a single CD in DGG's 'Originals' series.
It was one of the five CDs that I took to my dealers when auditioning to buy a top-of-the-line Naim system 10 years ago.
