You know, now I am starting to think that archetype is even older in shojo... if TVTropes can be believed, that is:
Honey Honey
I watched this show back in the late nineties but I had forgotten about it until I came across that page as I was gathering information about classic shows. After thinking about it, I think the article is right and the main character fit the tsundere type. Nevertheless, it has been a while since I watched it, so my memory is a tad foggy.
I also remember the Ranma shipping wars and they were incredibly stupid. Apparently Ranma couldn't end up with Akane whye she was psychotic and violent and never trusted him, and he would deserve a girl peaceful who would never hit him or jump to conclusions... like Ukyo or Shampoo. What? (to people who has never read or watched Ranma: Ukyo or Shampoo were way, way more violent than Akane, and couldn't care less about Ranma's feelings).
Tsundere- type characters often are a target for handdom hatred: Akane (Ranma), Shinobu (Urusei Yatsura... which is hilarious because the other main female character is also a tsundere), Misty (Pokemon), Asuka (Evangelion), Relena (Gundam Wing... albeit she is hated by yaoi fangirls for being main's character's official love interest and not a man)...
Sometimes I would like going back to the seventies and finding out if fans also hated Sayaka Yumi and the other tsundere characters of the Mazinger series (Jun Hono, Hikaru Makiba and Maria Fleed) for not putting up with their love interests when they did something stupid or sexist, back then when the tsundere archetype were new.
Regarding Sasuke... Never I liked him, honestly. I understood the appeal of the silent character, but I wasn't too interested on it (and actually I was pretty sick of seeing silent, cold and somewhat jerkish main characters back then). And that was before he started going mad.
Sakura behaved like an average twelve-year old girl: she fell in love with the "cool and rebel-looking" guy in the class and thought the power of her love could heal the scars of his heart and soul... and then she got to spend time with him and steadily realized the reality. Not matter how much SS fans want believing otherwise, she had forsaken any dellusions of Sasuke being her charming prince before the end of Part I.
