Callaway Fusion Wide Sole Vs Big Bertha Fusion

[Prodigy]

I am looking to buy a new set of clubs that is friendly for a beginner like myself. Several people suggested the Callaway Wide Soles, as they have a very forgiving hitting area.

I ran across two different types of Fusion Wide Sole. What is the difference between the Fusion Wide Sole and the Big Bertha Fusion?

Please note that I am a beginner and I will be purchasing a steel shaft. Thanks in advance for the help.
