Kid was never paralleled with Zoro. He was always shown as Luffy's rival and a foil to Luffy. Oda just had to split them up because Yamato.
imo Kid is on par with Luffy. I think Zoro's supernova rival will actually become Law. Similar to how Mihawk had a rivalry with shanks, I think Zoro is going to have a rivalry with Law. As after all, Law and Zoro are the strongest swordsmen of the supernova and Oda hasn't definitively established Zoro over Law. You can say Zoro> Law, but at the moment, its just speculation.

Technically all supernovas (including Zoro) are Luffys rivals, what makes Kidd any different?
