I like both, but my favorite is Serena.
Venus is like ice and Serena is like fire. Venus is mor elike grass courts, calm and steady, while Serena is more like hard courts, explosive and fast.
Best Forehand- Venus, her forehand at peak was impossible to return.
Best Backhand- Serena's always. Venus had agreat down th eline backhand, but it's been gone for several years, while Serena's backhand has always been deadly.
Fittest (Fitness)- Both are prone to injuries, but Serena is fitter. Venus now is just washed up.
Quickest mover on the court- Venus has better reach and takes small steps, but Serena can run more so I don't know. It's a tie.
Best Server- Serena obviously. Venus' serve is overrated. She hits tons of double faults and not as near aces as Serena, even at her peak.
Best Defender On The Court- Serena's defense is surreal sometimes. It's all mental though, she is a fighter.
Best at turning defense into attack- Again, Serena. Venus is more of a situation player where she either attacks or defends. Serena is more versatile.
Best Personality- Even though I like Serena better, I'll say Venus, because she is humble.
More Entertaining To Watch- Serena because she is more dramatic and her game is more interesting.
More Temperamental- Obviously Serena. Venus looks very calm on the court, while Serena can be immature sometimes and say things she doesn't mean.
