This is the stuff Reddit threads are actually complaining about — not the headline specs.
Enterprise buyers requiring SOC 2 Type II today should confirm current certification status before procurement — it's actively being pursued, not yet complete.
The LMS integration that makes Synthesia the corporate training standard is locked behind custom Enterprise pricing, not available on Starter or Creator.
Both are talking-head/avatar formats — great for training, ads, and explainer content, not a replacement for narrative video production.

A read of real HeyGen vs. Synthesia threads — not a generic AI summary.
Reddit's take splits cleanly by use case: HeyGen "wins on realism, not even close" for anyone chasing lifelike avatars, while Synthesia keeps the edge for non-technical teams building straightforward training videos — and both get called out for advertising "unlimited" plans that hide real credit caps once you dig in.
“HeyGen wins on realism, not even close right now”
“if your team is non-technical, Synthesia still has the edge on usability though, it's built for exactly this kind of use case.”
“synthesia just raised their prices again and heygen's free tier is basically unusable now.”
“HeyGen has better avatar quality but don't know why output sucks all time, but you're paying for realism.”
“The price gap comes down to what "unlimited" actually covers. heygen says unlimited but the good stuff runs on separate monthly credits”
