Except aging isn't the sole factor affecting one's capability. Battle exp and Jutsu acquiring / refinements play a huge role. One would be a looney to say the sennin mode-less Jiraiya (when facing Hanzo for example), in his supposedly "prime age" is stronger than the 50 yr-old Jiraiya.

Senju + uzumaki doesn't say anything. Being senju + uzumaki you would think Tsunade has tremendous stamina, while she has a measly 4/5 compared to the many 5/5's of unnamed descent.
