Serena seems high to me. The men are similarly accomplished and did so overlapping their primes while Serena had no rival. And Novak, in particular, ended up with more Grand Slams, more Grand Slam wins, more wins, more wins against top 10 players, more weeks at #1, etc. than Serena did I get Novak is not well liked, but there really isn't much of objective measure to put Serena ahead of Novak except for doubles, which they didn't even mention. Had they used the doubles with her sister as a tiebreaker, I think it could at least be defended, but the snippets they put, especially the pregnancy stuff, make it much less about the actual sport of it.
