Give a couple of examples of idols who you think are the best in their group. Only one idol per group. The group doesn't have to be your faves but you should know all the members (otherwise thinking one member is "the best" doesn't mean much). Except for that you can answer with whatever groups you want.
I'm intentionally using a vague term because I don't wanna accidentally influence anyone's answer. Simply answer whichever member you'd label as "the best".
Disclaimer: This is not meant to put any idol down. Threads purpose is to see if there are any unexpected trends in people's answers. What makes people consider an idol "the best" etc.
