User blog:Airboy16/Mix and Match, or organize?

Lately, I've been noticing that this wiki sometimes puts all 36/37 contestants together as one library of contestants, as some other users rank their favorite characters this way, and the main wiki trivias put both casts together as one library.

There's also a few users that organize the cast by first generation and second generation.

I'm wondering: Which cast organizing method is more workable?: 2 seperate casts, or one giant bundle cast mixed in?
