Pick OpenAI Whisper if you're a developer and researchers who will run a checkpoint locally or on a Space and accept open-model quality. Pick Piper if you're self-hosters who want a file or a speaker on-device. Skip OpenAI Whisper if you're people who want a hosted voice product with a published credit card (ElevenLabs) and will not install Python or open a Space.
