The short version

Only HeyGen has a free tier, so it costs nothing to try first.
Each has a real cost: Avathon the company rebranded from SparkCognition to Avathon and narrowed its focus after repeated reported layoff rounds, so reference checks and roadmap commitments made under the old name need reconfirming.; HeyGen avatar movements feel unnatural in longer videos and repetitive with limited emotional expression, appearing stiff and robotic after 60 seconds
They diverge on capability: Avathon covers Renewable Suite, HeyGen covers AI avatars.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Avathon

The company rebranded from SparkCognition to Avathon and narrowed its focus after repeated reported layoff rounds, so reference checks and roadmap commitments made under the old name need reconfirming.
Headcount is in the low hundreds against a product portfolio spanning renewables, vision, predictive maintenance and document AI, which is thin coverage per product line for enterprise support expectations.
Model accuracy depends on having enough labelled historical failures, and sites with short data history or poor maintenance record-keeping get generic anomaly detection rather than useful failure prediction.
Nothing is published about pricing or asset-count thresholds, so there is no way to judge whether a small fleet is even a viable customer without entering a sales cycle.
It sits on top of your SCADA and CMMS rather than replacing them, so the integration and asset-hierarchy mapping work is a real project cost that the software subscription does not cover.

HeyGen

Avatar movements feel unnatural in longer videos and repetitive with limited emotional expression, appearing stiff and robotic after 60 seconds
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
