Alright, so ToP people who definitely scale to the 3-A stuff:
Freeza: No shit.
Hit: Should be obvious to anyone who's been watching the show.
Android 17: While I don't think he's quite as strong as he's been getting credit for, he's still comparable to pre-ToP SSB Goku, and managed to put up some fight against Toppo. Notably though, still not as strong as an exhausted ToP Golden Freeza.
Toppo: Second strongest Pride Trooper, base form matched SSB on two separate occasions.
Dyspo: Third strongest Pride Trooper. Matched Hit and SSG Goku in his base, required the combined effort of Golden Freeza and Ultimate Gohan to defeat after he powered up.
Caulifla and
Kale: The latter via her transformations, and the former
possibly only via SSJ2. When working together, these two managed to overpower SSJ2 Goku after he first broke his limits, and put up a solid fight against limit-broken SSG Goku. Their powers combined and multiplied by "only" tens of times was enough to body the same SSG Goku.
Kefla: For her base, see above. For her SSJ1 + Berserker mode, she put up a fight against and eventually defeated limit-broken SSB Kaioken Goku.
Ultimate Goha: Comparable to Golden Freeza when going all out, managed to overpower Dyspo after he had powered up.
Koichiarator: Fought Ultimate Gohan and two SSBs.
Anilaza: Should be obvious from his fight, notably superior to Koichiarator.
There are other ToP characters who I think should or should not be 3-A, but this is just a list of the most obvious people who should stay where they are. Combined with the obvious downgrade list, this should make discussion a lot easier.
Let me know if anything major should be changed.
