Differences the Project RS2 Transport and the (newest) Jay's Audio CD2 Mk 3

@jaymark and @charles1dad are owners of the Project PS2 Transport and loving it.  I am between the Jay's Audio CD2 Mk3 and the Project.   However, did anyone compare the NEW 2019 Jay's Audio CD2 Mk3 rather than the prior model Mk2?  Steve Guttenberg reviewed them both and found significant improvement in the Mk3 version sonically.   How close are they now as the Jay's is $2500 and the Project with LTA power is closer to $4,000 (with taxes)?
