It’s a difficult one. Rosenbaum is excellent as young conflicted Luthor, the one who is still Clark’s friend but gradually makes more and more choices that make him a ruthless villain, but IMO he’s not very good as the finished product, and his having been a major part of Clark’s life makes their relationship very different.In a movie. The Luthor from Smallville is the one I think nailed the character the best. From what I understand, though, the movie Luthor was based on the one from Smallville.
My personal favourite version of Luthor is Clancy Brown, but of course he’s animated.
Hoult does a brilliant version of Luthor at the beginning of his villainous career - incredibly talented and resourceful but not yet having gained the calm and patience that come from experience, and unable to conceal the childish petty envy and hatred that are the core of his character. He’s most based (from what I’ve read) on the Grant Morrison comics version of Luthor, who is a little older and wiser but still very much the same man at heart.
