If I had to choose, I think I prefer soft voices. I like it when they play gentle roles with a gentle voice, and their "s"-style acting is great, too!
I'm so happy to see someone list Takashi Kondo and Junichi Toki as their favorite voice actors—I like them, too!
I can never pick a favorite... Soft voices can be so soothing and adorable while deeper ones have this irresistible charm that makes a character sound so mature and attractive. I guess it really depends on the character and the way they speak!!! As long as the voice suits them I'm more than happy either way hehe. ♡(˶˃ ᵕ ˂˶)
