Ao > Shisui.

Simply because Ao live longer than Shisui. Shisui is daed man, he will never be able to compare with Ao. Not to mention the newest feature that just got updated in Venezuela server that allow you to upgrade Ao to 6 stars and make him become god Ao with gatling gun and robotic arms that can absorb jutsu. While Shisui is unusable when you upgrade him to 6 stars because he lost both of his eyes after that and most importantly, he is daedededed.

Dude... really?

Some people just can't read sarcasm and easily baited :)) LMAO
