Reasons why I think Sakura will surpass Tsunade
1. Talking about storing chakra for her real power, storing chakra for someone like sakura who has an average chakra reserve is unlikely for any jutsu we've seen her use.
2. Tsunade stated that her students who are medical ninjas do not engage in battle only if they master her mitotic regeneration jutsu. For Sakura to engage in battle means she should have something like Tsunade's jutsu or even more. I'm not sure sakura has mastered BYAKUGOU, because according to madara, is a jutsu of the senju clan which hashirama possessed; I think she's created a jutsu like that or even a more powerful one than Tsunade's.
The future generation will always surpass the previous.
