Haven't listened to recordings of this work enough to have an opinion on which I favor, but because a poster 2 years ago referred to Gramaphone magazine and the Penguin Guide, I feel entitled to pass on the opinions expressed on my favorite source of reviews, Classicstoday.com, FWIW.
The Rostropovich/Giulini recording was judged the least successful of Rostropovich's many recorded performances, but the fault was attributed to Giulini ("My God, he's boring!"). The Rostropovich collaborations deemed best were those with Karajan, Talich and Ozawa. Historic recordings judged to be great performances but with poor sound are Casals as both soloist and conductor of the Barcelona orchestra and Feuermann/Sargent (both on Naxos historical). Also favorably cited are Ma/Masur (Sony), Helmerson (BIS) and, more recently, Queyras/Belohlavek (Harmonia Mundi). Recordings by famous cellists that were deemed less successful are Ma/Maazel and DuPre/Barenboim. No comment on Kliegel's recording, but the Classicstoday reviewers generally regard her work highly.
