For 30–45 minute weekly episodes: ElevenLabs generally gives the most natural voices, fast in-browser editing, and clear commercial rights on paid plans. Gemini (Google) can be more cost-effective at scale via API but often needs custom batching and workflow work. Practical test: render a full episode start-to-finish on both (editing, exports, and cost) before committing.
