Okay I did find a way to sort them on WWE.com
Apparently Kane and Big Show are officially Raw Superstars, and Daniel Bryan and AJ are officially SmackDown Superstars.
From: SmartMuffin | #096
In general, the WWE title is RAW, the WHC is Smackdown,
This doesn't really work because you have people like Bryan, Henry, Kane, and Jericho fighting for both within the same month.
