I will grant you that Zoro vs Mihawk will be the highlight of whatever arc it's in. I do think it's a special case because it's Zoro's main dream to defeat Mihawk, so it can't be overshadowed, even by Luffy.
If Zoro fights Kizaru and wins, then Saturn will be stronger and Luffy will beat him. If Kizaru is stronger or Luffy doesn't defeat Saturn, then Zoro will not defeat Kizaru. Maybe Luffy will, or maybe Zoro will fight him and get interrupted or lose. The fact is that Zoro has never defeated a stronger opponent than Luffy's in a given arc even one time in the entire series.
As far as the hakai thing, Zoro took two seconds of it and then got saved by Law, and even then it broke every bone in his body. If he took the whole thing, he would have died. I saw no one looking at Zoro in awe during that moment.

Zoro defeated Morgans while Luffy defeated Helmeppo so it is not true that Zoro never defeated a stronger opponent.
Law never saved Zoro from the Hakai, it was Zoro who deflected Hakai.
And I gave you a link for a thread that explains why Zoro always was, is and always will be stronger than Luffy. Lemme know when you read it.
