[in terms of Arsenal/power] Which one?

[esenn1]

1- Sakura

2- Sai

I personally think they're more or less at an equal level

Clearly its sai he was working for the roots hence has special training in various ninja arts
He has lots of jutsu's in his arsenal than sakura hu just keeps punching things and nothing else
Being under direct command of danzo he probably knows some sealing jutsu's

 

[DrProof]

Sai. No competition really. He would defeat Sakura mid-high diff.

 

[phantomlord22]

sai
he is stronger, just saying xd
