So far, yeah. She was the one locked outside of her own treasure room whereas Cracker was about to send Luffy to next world has it not been for Nami's help.
As far as skills go, Cracker is miles ahead of her. Smoothie has shown some great flying slashes during WCI, but all of them were due to her absorbing other people's fluid or something which made her big enough to perform such attacks. Cracker could go toe to toe with G4 Luffy and even force him to go on defensive. The same G4 Luffy who put down Doflamingo, one of the most versatile fighter on series.
