Kind of a weird and difficult question to answer, but what do you guys think the most suitable game is for each of the two available player characters for each release is?

RSE/ORAS
>Brendan - Sapphire
>May - Ruby

>Can't decide

HGSS
>Ethan - Gold
>Lyra - Silver

BW
>Hilbert - Black
>Hilda - White

BW2
>Nate - Black 2
>Rosa - White 2

XY
>Calem - Y
>Serena - X

Sun/Moon
>Can't decide

Bonus points: The most suitable starter Pokemon for them (be it the anime canon, or just personal preference)
