This has to do with Chopin editions.And if you are a really advanced pianist, and have a scholarly knowledge of Chopin's editions, which version would YOU be playing?Frankly, I am not sure the listener could easily detect the differences . For one example, some left-hand notes in the one edition are single notes, whereas in the alternate edition they are octaves. Not hardly enough to get all that excited about, right?
See if your library has a copy of the Henle Urtext of the waltzes. Whichever they include is probably the most "correct," as supposedly no edition is more researched than the Henle.
