Anything written with GS in mind will sound superb on a VA. Roland started the whole GM/GS thing and many sequences in the early days were matched up perfectly with their gear. In fact the XG stuff sounded poor in comparison till programmers started making sequences specifically for the XG sound set.
My ears prefer GS to XG anyday of the week.
