not really.
ISDS was overhyped hard. It's not a beyond high tier move at all. G4 was at least as powerful. Karyudon was more powerful, imperial archer was likely more powerful, Marco and Kata high end attacks too. etc etc. Sanji beef burst is stronger than DR ISDS by a good marfin too.
ISDS was "just" an high tier move, and a normal/average one.
Also Zoro Ashura , his best attacks, was only enough to make a slight scar on Kaido. It was definitely a good attack but wasn't enough to really hurt a beast like Kaido or Big mom.
Law and Kid with their awakening showed moves stronger than rooftop Ashura. Moves which really hurt deeply a top tier with monstrous durability. And moves who took her down.
Zoro ashura is not something he can really spam while Law and Kid showed multiple techniques with awakening
So offense wise current Law and Kid > Rooftop Zoro.
About endurance : yeah rooftop Zoro was already a monster. The two others weren't bad at all but Zoro stood out the most.
But Soon after Law and Kid showed that they were huge tank. The way kid just tanked BM last attack is crazy. Hera + Prometheus huge lady injured him but barely. And it's likely the last attack of a Yonko.
So now Kid Zoro And Law are more or less at the same spot : insane offense, better than all high tiers, insane endurance better than all high tiers, but except that their others stats are not far apart or are at YC1 level.
Rooftop Zoro lacked the offense to be really above high tiers level. But he was already solid af.
