maintenance of the piano black sf concertos

I am in the market for a pair of sonus faber concertos. I am still deciding on the black piano finish or the oak finish. To the audiphiles who have the black piano may I direct this question to you. Do you fell that the lacquer finish deteriorates more compared to the wood? Maybe more prone to scratches? Or harder to maintain?

If given the chance would you buy the black piano finish again?

Thanks,
