I tried to find data but couldn't quickly, so maybe someone else can find a comparison study. So instead, fwiw, anecdote: I work for a film production company and we ingest assets all the time from high end VFX houses. It's always from Unreal / used in Unreal in my experience. That's in LA/ Hollywood and high end productions. For all I know they use a lot of Unity in Bollywood or Europe.
