The professional "design" is too busy and noisy, distracting me from title. The call to action is tiny. The "ugly" design increases the lettering to a larger %

The professional "design" is too busy and noisy, distracting me from title. The call to action is tiny. The "ugly" design increases the lettering to a larger % of the total graphic. A design with these changes, and graphics that are a better abstraction for the message, would likely perform much better. (tl;dr pretty design != good design)
