Who is a better tennis player, Venus or Serena?

Great question! I really like this question because it’s difficult to decide, and I can tell you a bunch of ways you might want to approach it. First, I can provide some details about the two women you’re comparing. Venus is taller, she has a longer career, and she has won the most Grand Slam titles. But Serena has won the most singles titles in one year, and this is the tie-breaker for the WTA rankings.  How can I be more helpful?
