Im more with Paltop on the tsundere thing, I dont go so much for A or B and more on a percentage scale
Even though I am definitely in the camp of there being "Types" of Tsundere as TV Tropes says, I think that within the types there are levels of severity, a high-low scale within the broad classification of "Type." In my original post, most of the Tsundere I listed as my favorite were Type A but the extent each one was a "Type A" was different. Tsundere like Ryouko Ookami are higher up on the list than say Kurisu Makise or Kyou Fujibayashi. All three of them are Type A, but there is nuance within the classification as one could say Ookami is "more" Type A than Kurisu or Kyou (or in my later post, Kagami Hiiragi as well). And on top of that, Taiga Aisaka is even stronger a Tsundere than Ookami. Both are still Type A, but Taiga (along with the rest of the Tsundere Wonders) are "more" Type A than Ookami, and far more so than Kurisu, Kyou or Kagami. I don't know exactly what the low end of Type A would be, but I know that the "Most Type A" of the Type A's would be the Tsundere Wonders. TV Tropes has an article almost directly relating to them (and those similar), under the name "Shana Clone":
do y'all fine bunch of niggas think of Kuroneko as tsundere? just being a curious George
Relating to this idea of there being a scale of intensity within the classifications, I do not think of Kuroneko as a Tsundere, no matter the type. I think if her as a Kuudere, because of her generally mature nature as well as her approach, aloof and distant while barely ever even raising her voice. Her Dere is hidden with witty comebacks, aloofness and the silent treatment, which is par for the course with Kuudere. However, concerning scales I think she is a "weaker" Kuudere, by which I mean not super far off from Tsundere. I say this because her calm and collected facade is pretty easily shattered, and she gets flustered more easily than she is willing to admit. On the otherhand, someone like Senjougahara is a far stronger Kuudere, because she is nearly unflappable. Her sly wit and aloofness seemingly cannot be broken, not even if one was to take a stick of dynamite to it.
So while I think there are concrete classifications, I think there is leeway within them and a scale within the boundaries.
