I personally have never read or seen the manga/anime Hana Yori Dango.... HOWEVER! I have watched the Korean and Japanese adaptation and I loved both. Tsukasa is most definetly my favorite character and the actors who played him were also fantastic! Matsumoto Jun and Goo Jun Pyo are great actors who totally understood Tsukasa true character and personality. I will rewatch the Japanese and Korean- Hana Yori Dango dramas for years to come!
I really recommend that you either read the manga, watch the anime, watch the Korean drama, the Japanese drama or the Tawainese Drama (Never seen this one?)!
