[MCU/Infinity War] Why does Thanos acknowledge Stark by name?

I get that he knows who he is because of the soul stone, but why is Stark the only one he calls by name? He only refers to Dr. Strange as "wizard" and Spidey as "insect." So what makes Stark special enough to single out? Furthermore, why does Thanos have respect for Stark at the end of their fight?

Thanos is a lot of things but he isn't petty. He came face to face with the man who (from his perspective) single handedly destroyed part of his chtari army by literally throwing a nuke at it, killed one of his top lieutenants and highjacked his ship and then came within inches of stealing his Gauntlet *while he was still wearing it* and then yet still manages to survive after getting in a moon planet shattering fight.

From where Thanos is standing, that takes some serious chops and Tony has earned his respect.
