Ummm difficult.... They are all excellent musicians
For his cheerful character, that of Yo Yo Ma.
Casals, Rostropovich, Fournier (recorded in Basle Cathedral), Schiff, Bylsma and the Maisky´s first record, they all seem perfect to me in terms of virtuosity, although I wouldn't know which one to choose... perhaps Bylsma's version. On a technical level, I admit that I feel more attracted to "modern" recordings, so the Casals and Fournier recordings are the ones I listen to the least.
Gavriel Lipkind and Queyras are perfect for me and on a technical level their recordings are simply spectacular (Queyras' version is recorded at the Eglise Saint-Cyriak and I think I remember that the engineer used DT990s). Both are very careful recordings and their presentation is extraordinary (it is worth the money it costs)
Wispelwey I have always thought that it is the most correct "temporarily" since it uses a Baroque cello with "gut strings" (cuerdas de tripa, I don't know if the expression is correct) and I like to think that, if Bach ever got to hear his pieces, it would be with one of these instruments (perhaps I'm wrong).
But the one I like the most and my first choice is Maisky's second recording. He is energetic and makes me feel very happy. It is very different from all... comparing his two recordings I feel like he evolved from an instrument virtuoso to a musician.
I really like when something is recorded in cathedrals or churches... these places provide spectacular acoustics.
Like allways, excuse my poor english and be soooo boring 😞
