Mozart Piano Concerto 21.


I'm looking for Mozart Piano Concerto #21. Which ones are worth owning?

thanks in advance

I also own the Lipatti, which also has a nice performance of the Schumann concerto. I don't mean to knock Schiff too hard. I do like his Bach interpretations.
At the risk of sounding out of touch, what is the panel's opinion on Vladimir Ashkenazy's recordings on Decca ? The recording is not perfect (early digital), but I really like his flair. Am I missing something ? I'm no classical buff, but it sounds like a good performance to me.
