*SORTA OLD SPOILER ALERT* Who is the best Unova Champion?

Lord N (King of Team Plasma, Ghetsis' adopted "son", and one of the only people that can talk to Pokémon. He is also the "Hero" chosen by Reshiram/Zekrom, depending on version.)

Alder (Benga's grandfather, Marshal's mentor, and the only Unova Champion in the Pokémon World Tournament.)

Iris, "The Girl Who Knows the Hearts of Dragons". (Drayden's adopted granddaughter, she was born in the Village of Dragons. When she becomes Champion, she wears a cool Princess outfit.)
