This is the first thing I see after opening my computer many hours later. I was certain you wouldn't actually do it, you are not real
Anyways, if you buy the "enough raw power bypasses infinity" argument (which gets the only major issue out of the way and Hoshino has already brute forced a form of protection that is in summary reality warping miracle protection), then Hoshino and Hina bulldoze both of them since they comfortably out speed (mach 3 vs 7, there's also a lightning and laser reaction reaction feat for Hoshino but that one is weird to use even if legitimate since verse full of bullet dodgers), while both scale to
Binah's cloud clearing in the raid opening (and are stronger than Binah), and you can also apply continental strength to both of them through false sanctum and volume F stuff
They should both be able to withstand unlimited void as there are various mental effects both in gameplay (various things student's can do and use on each other, primarily) and from things in the story (false sanctums) that can be resisted either entirely or to a degree (Ex: Myouki Kurokage's intimidation / compulsion and what it causes is not resistable, but student on student powers can be either fully or somewhat resisted)
Malevolent shrine just tickles them, and iron horus has endured stuff that makes dismantle look like a rusty blender with one blade so it does not have a threat to destroying it
World cleave would depend on how you view it. If you think it's a traveling just very strong cleave, then Hoshino can definitely block it with how much she has blocked when both in perfect condition and fatigued (such as Binah's stone vaporizing mouth laser when in perfect condition, and constant volley's from Hina when fatigued). If you view it as it pops up where Sukuna aim's after he finishes chanting and just spatially cuts whatever is where he aimed, then it would depend how fast he is taken out of the fight or when he decides to use it, and if you do not view it as spatially cutting then it does not matter (have to specify since every alternating jjk fan thinks it works in a different way for some reason)
Hollow purple showed itself to not really erase matter so that is out of the way
Fuga should not be a major threat either, and massive flame blasts or heat greater than what fuga did (not in area, but raw power) is regularly able to be taken in, such as Hod's laser and Chokmah's fire. Also, very close exploding napalm for Azusa (a mid tier student), is an afterthought for any effect it has
Gojo and the one time he crushed the space around a curse user and when he crushed Hanami could definitely work, but it's not something he's going to think of using with what he usually does for fighting
In summary, Hina and Hoshino just have a way around most of what Gojo and Sukuna do and overpower them. There's more like whatever student's being able to exist in the Throne of Naram-Sin, a "chaotic realm where dimensions, time, existence, and non-existence are mixed together without ever settling" (word's of Plana in Volume F chapter 4) could mean / apply and there's game mechanic related stuff but I think overpowering and having answers to the two's abilities should help enough without needing to get into Hoshino and Hina's extended special stuff so far (they probably won't get more content for a while after Volume 1 Chapter 3, or at least Hina is definitely sidelined until a Gehenna volume happens)
