No, tsunade has shown us how superior she was to sakura when she healed shikamaru INSTANLY with a finger while sakura was healing him for almost 3 chapter (that goes to show she is leagues above sakura in chakra control)
- tsunade eventhough healed more times than sakura, actually engaged in combat, giving ohnoki a large portion of her chakra, healing the kages perfomed the same feat of summoning katsuyu's body when she arrived at the battlefield
- tsunade is senju (so by defalut she should have more chakra) meaning more chakra to use on her fists thus stronger punches
- tsunade has more experience
I think kishi intended for sakura to surpass tsuna though but failed at it cuz feats says otherwise
