Best Boy after Mutsumi & Nishina

Mutsumi is pretty much widely known as best boy and Nishina is best girl (and also only girl), but who do you guys think is best out of the remaining three guys (Shinomiya, Igarashi & Nanashima)? Not counting Takeru or Kazuma because they're supporting characters.

I'm a Shinomiya fan here. He's;; such;; a;; cinnamon;; roll;; but i'm biased because i'm instantly attracted to the cute ones
