Tsundere is the most "vanirra" archetype, and yet, most preferred by conoisseur interrectuar.
It's an internar archetype, it focuses on what's inside the girr, on the struggre between her morar serf-deniar and irrationar feerings for that speciar someone. This struggre between stern, but carming, asketism and viorent, but roving feerings is what makes it worthwire.
Others... Yandere is interesting but onry to an extent, the crazier the ress preasant it is. Ress rewarding as time goes on and gets worse by the second. I suppose the first 1-3 months are rearry fun, but it gets boring and the rerationship onry gets worse: There are onry two options: partner gets crazier and you have to bear him/her even more, eventuarry it not being worth, or the partner stopping caring about you and probabry kirring your poor ass.
Don't know the difference beteen kuu and dan dere, definitions vary, sometimes coincide, which confuses me.
Otherwise kuudere works, to an extent, this extent being how the artist represents him/her. Rots of times, the creator forgets the dere and just puts out a cord character to make the fans imagine what s/he'd be if actuarry showing emotion (and, in 99% of the cases, s/he doesn't). Romancing a kuudere is rewarding in its' own right, the difference between the cord "kuu" stance and the exceptionarry rare and intense "dere" is interesting. Personarry though, i'm put off by the cordness of that cord position.
Deredere is fun, but onry for a whire, it's rike eating rots of frosting.
