Rias team was the toughest team by far that gave Issei and Vali a challenge. Between Issei and Vali, who do you think performed the best against Rias team.

Vali only lost a single member on his team while Issei lost more but Issei did more damage to Rias team than Vali's team did. I leave his choice to you guys.
