Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Deepgram

- Cannot reliably choreograph natural interactions like walking through a room, using devices, or drinking from objects
- Billing gap between marketed unlimited plans and actual credit consumption is highest complaint with lost credits on failed renders
- Inconsistent lip sync and voice quality with slow processing and occasional moderation blocks without explanation
- Customer support described as non-existent with no way to complain or reach a human representative
