I voted for Joe. Winning the Tour finals is the ultimate achievement and I always feel he is underrated
Slam titles definitely come before tour finals triumphs for me.
Clearly Joe has achieved that as well this year. I very much admire his doubles prowess but ultimately he didn't get my vote partly because we are talking doubles rather than singles and also he had already won Slams and been WR 1.
I generally vote for who has made the biggest impression on me during the month / year.
The other group has 3 more votes so hoping 3 folks at least are just holding back. By all means watch the end of Netherlands and Argentina, but dont miss out here!
