That's pretty common among TTS services and engines. Most people want a female voice for their personal assistant/ebook reader/whatever, so the male voices don't seem to get as much tuning. As someone who happens to prefer a male voice on my apps, it's a little frustrating.

I don't know how much is tuning and how much is personal preference but I plugged in some different texts and I'd probably default to Amy (English, British).
