Feng-GUI vs Plerdy
These two don't answer the same question. Plerdy records what real visitors did — it needs a script on a live site and traffic before it can say anything. Feng-GUI predicts where the eye will go — it works on a URL or a mockup, before launch, with nothing installed. Many teams run one of each: predict before, verify after.
