Vissers does, overall, have better muscle shape and attachments than CowaBumga but he seems to be a "by the book" kind of guy that overly relies on other's advice without having an "in the zone" intuitive sense that takes over in the actual implementation of the direction he is given. Even when posing it looks like he is thinking through the slightest movement he makes instead of exhibiting a second nature flow to his movements, which should be the end result of practice.
