Okay, after listening to both the Cello Suites (Fournier) and the Solo Violin Sonatas & Partitas (Podger), I can now say that I would prefer the violin pieces to the cello set.
The sound of the violin, at least from Rachel Podger, is enchantingly beuatiful, and lighter, not as dark as the cello - which all adds up to my ear becoming less tired from extended listening, which, on a desert island, would be an issue.
