Harden is a better scorer, 3 point shooter, free throw shooter and arguably a better passer also (they average the same number of assists). Jokic has never led the league in scoring or assists. You can't be in the GOAT offensive player conversation with a resumé like that. Harden led the league in scoring three times and in assists twice. You could even argue that if you correct for Jokic being a big man that his overall FG% advantage and rebounding advantage are a little underwhelming also. Harden also has more 70+ games seasons played than Jokic has seasons played in total. Jokic playoff numbers are skewed because he's only been in the playoffs six times. Like someone said, a CP3 hamstring injury is really the main case for Jokic.
