It comes down to fit, not a single winner: Deepgram leans into fast speech-to-text with diarization and custom vocabulary, while Gemini Omni is built for video & audio work. Deepgram edges the Editor Score (4.3 vs 3.7), but a 0.6-point gap rarely outweighs picking the tool whose features match your work. Gemini Omni is the lower-cost place to start thanks to its free or freemium plan; the other is worth a trial if its feature set fits better.
