Her strength was stated to be even greater than Tsunade's was, and she was able to use the seal more efficiently since she wasn't using part of it to stay young like Tsunade was. She also had more time to store more chakra in the seal unlike Tsunade, who had used it much more often over the years. By the time Gaiden came around, there is no doubt that she has surpassed her.
