I'm not comparing her to men's players rather than comparing the competition of who they have played. Roger has had the most prolific men's tennis career ever playing during his best years against the likes of Nadal and Djokovic. That's like if Tiger, Nicklaus, and Palmer all played at the same time. And for the record I believe Serena in her prime could compete against and beat a lot of the men's players.Well, to be fair, or unfair rather. You can't really compare Serena to the men's players. She can't compete against them.
