Which of these men is likely to find women more interested in him: A man who flirts first, and figures out whether he likes you later, or a man who figures out whether he likes you first, and flirts later?

Which man is likely to find women more interested in him? A man who flirts and sexually escalates before he's figured out whether he likes you as a person, or a man who tries to figure out whether he likes you as a person before flirting?

I imagine a lot of responses are going to be "Well, he should be flirting and vetting simultaneously" but that's not the question. These are the two options. And, why do you think one would be more successful than the other?
