Audirvana VS Audirvana Studio

Has anyone compared these two to each other?
I don't think new users are offered the Audirvana anymore. And if the existing users upgrade, it is only Studio. So I don't think people can compare them on the same PC/laptop.Hoping that existing Audirvana user can chime.
Audirvana is still supporting the non-Studio version.  A new upgrade was just recently released.  However, new sales seem to be for A. Studio only.
