Short answer: ElevenLabs offers the most natural, expressive TTS and straightforward voice cloning—best for a consistent 30–45 minute host. It has a Studio editor for retakes, prosody controls, and predictable per‑character/subscription pricing. ChatGPT excels at writing and iterating scripts, but its built‑in voices aren’t as natural for long-form hosting and require extra steps for final audio.
