DB and Kane appear on both, but lean RAW (because that's where Punk is and that's who they're feuding with).
Show leans RAW, because that's where Cena is.
AJ goes with DB and Kane.
In general, the WWE title is RAW, the WHC is Smackdown, US is RAW, IC is Smackdown, Cena is RAW, undercard divisions (tag team and divas) are Smackdown, etc.
