Strengths
Fine-tuned specifically for natural rhythm and stress, which is where cheaper models usually fall down.
A compact, well-differentiated catalogue rather than dozens of near-identical speakers.
Materially cheaper than the $0.03/1K bracket while still sounding natural.
Focused rather than broad — it does one language well.
