He's good in voice acting. I also cannot understand myself from not liking him to the fullest.
I first heard him Kuwahara Jackal in Prince of Tennis.
He's also known as HIEI in Yu Yu Hakusho.
He also acted Madarame Ikkaku from Bleach.
My favorite role of him is Kouyu Ri from Saiunkoku Monogatari.
Anyway, in the end, this is just my opinion.
