User blog comment:Solmonster, the Daily Phantom/Ranking of the MCU Main Villains from my least favourite to favourite/@comment-30386163-20180520163933/@comment-30072618-20180523064816

Winter Soldier, if you ask me, would rank between Ultron and Ego. However, I didn't include him because he isn't a main villain and I don't consider him a villain at all.
