Sakura becomes hilariously broken when bloomed, but we shouldn't get that for at least 6-10 more months.
Honorable mention to bloomed Daisy also.

Alpinia is also a strong contender cause she has Speed Versatility and her Bloomed Form is also quite Powerfull.

It also depends which strategy he likes...Also waifuism is a big factor as well

Defensive or Offensive? Skill Activation Squad? Debuff Squad? Speedy Pest Controll Squad? Counterattack Squad?

We need some more Information what type of Girls and Gameplay he likes
