People answer a question that hasn't been asked. The question is not who is a bigger legend, more liked, etc. The question is a bit vague, too, as present Haaland is not even fit to start games now.
If 'present Haaland' refers to that Haaland who scored 52 goals and won the Treble, and if the question is whether he is better than peak Aguero, there is only one correct answer to this question, personal biases aside.
