Avatar quality and realism
HeyGen is known for its most realistic avatars and lip sync, which is why so many YouTubers and advertisers use it. Its newest avatar models cost more credits per minute than older ones, so realism has a price on the credit meter.
Synthesia's avatars are polished and consistent, which is what corporate video needs. It offers 125+ stock avatars on Starter and 180+ on Creator, with 3 and 5 personal (custom) avatars respectively. For a talking-head YouTube channel, HeyGen usually looks more natural. For a 40-video training library, Synthesia's consistency and team tools matter more.
