Del Potro's USO 2009 run was definitely much more impressive but outside of 2009 he is kinda overrated. Even without injuries I don't see him winning more slams. Just look at his mental collapses against Djokovic in USO 2018 and Rome 2019. He missed a forehand on every big point in these matches. Both are chokers, but Thiem still plays better against the big 3.
