I mean really, which other female wrestlers in the WWE(other than maybe Trish Stratus and a lot of female TNA wrestlers) is willing enough to sell the pedigree from Triple H, then sell the Stone Cold Stunner from Stone Cold Steve Austin and then take multiple chairshots from Steve Austin all in one Raw show? Not to mention that her and Victoria are the only two divas in the WWE who've ever competed in a Steel Cage match. People often give Chyna too much credit for bringing a lot of attention to women's wrestling and breaking the gender barrier between Champion belts but I've never seen Chyna once competed in a Steel Cage or even a Hardcore match. She may have competed with mostly male wrestler but I've honestly never recalled Chyna ever competing in extreme and dangerous matches that only male wrestlers compete in.
My vote would be for Beth Pheonix...period...
