Foxwoods in a runaway for me. Foxwoods mold > RHC mold, and I'm not beholden to the WSOP set. I do like the WSOP early level chips but not the upper ones as much, but the Foxwoods uppers really stand well both on their own and in the context of the set.
I'm gonna say Foxwoods wins this by about 1.35:1.
