Which Dere do you want?

What is Revy of Black Lagoon? Something between tsun and kuu? Or just a less flashy tsundere (by modern standards)?

I believe quite strongly that Revy doesn't fall into any of these categories, and I've gone into it at moderate length on irc. Maybe things will change later, but she's not one.

I guess the kind I like the most are a moderate cross between a strong tsundere and a kuudere. The way I like to describe them are something greater than or equal to a 80-20 tsun-to-dere ratio. I like them to be more feisty, but for an actual reason. Shallow ones won't do either, they need to have some good depth. That means characters like Caska (Berserk), Asuka (Evangelion), Misaki (Blood Alone), Urumi (Onizuka), Inner Moka (Rosario + Vampire), Nah Hae-Young (Unbalance x Unbalance), characters like that.

It can't go overboard though, or be too vicious for no reason (see most Kugimiya Rie tsunderes).

But the best of them all is Ayukawa Madoka from Kimagure Orange Road. She's so much more than the average tsundere. There is subtlety and depth to her iciness, a deeply caring side that she hides for selfless and legitimate reasons. Not to mention she has brains to match her beauty. Fire and ice all rolled into one, and to say that you can describe her with terms like "tsundere" or "kuudere" would to a great disservice to her character development throughout the anime/manga.

I'll vote for straight-up tsundere. Iciness is good, but they can come off like emotionless dolls (Rei), or uncompromising bitches (Suzuka). Dere is nothing without the fire that masks it.
