Beautiful! I can easily tell the difference but that's cheating (after playing the sax of 17 years or so), the sax sounds a bit sharper and the oboe 'rounder' if that makes any sense, which makes it easy to pick out what is played by which instrument. Originally this piece is for two oboes, but this is a really nice variation and lovely to see a saxophone used for more traditional music, I wished more people would do that (but saxes are typically frowned upon for performing classical works in a 'serious' setting).
