I disagree. One it's not important what people remember most, that's just shallow, the quality of the role itself is more important. Two, I disagree on the case of Loki/Hiddleston. He was brilliant in both Thor and Avengers and in the case of Thor many people would say he was the best thing about it.
In short it's not a popularity contest, it's the role itself that matters.
