I legitimately can't tell the difference between the two male options. They sound like the same person. I can hear a difference between the female voices, but it seems like males really only have two slightly different tones of the same voice.
We definitely need at least one more. And maybe a tone slider. In a world where we can synthesize the voices and appearance of long dead actors I can't fathom why we can't have a slider to determine how bass our voice is.
