I think Duncan is more antagonistic than Jo on account that he's more loose and anarchistic, causing trouble whenever he feels it would suit him. Then again, Jo is indeed way more strategic.

Eva indeed wouldn't work well as a antagonist on her own. But I see her as a ideal 'lieutenant' type of character to the main antagonist, willingly doing his/her biding until late in the game until she instead gets rid of the main antagonist and instead usurps the role as main antagonist for the season's endgame.
