Wicked Good is no longer available for stores to get from their distibution warehouses. I picked up the last 4 bags from my local ACE and the manager saw that I had them. He told me that they are no longer going to carry Wicked Good but carry Kamado Joe.
Brethren JMSeltzer does a bunch of reviews on his Kamado Joe cookers and has a really good relationship with the company. He has confirmed that Kamado Joe has the same suppliers as Wicked Good for their lump charcoal.
Once I am running low on charcoal I plan picking up a bag of Kamado Joe Lump to give it a side by side comparison to Wicked Good.
